BEST GMT WATCHES FOR SMALLER WRISTS: 15 Great GMT Watches Under 40mm

4 hours ago

20 min read

I'm not sure if you've heard, but GMT watches have a sizing issue. Everyone loves a GMT, especially with bi-colour bezel. Will you use the GMT function? Maybe. But it looks cool. Especially that red and blue combo. Namely, the 40mm Rolex GMT Master II 126710BLNR, aka the Rolex Pepsi. But I hate it so much. Wait, wait, waitlist...that's not a sizing issue, that's a sunnuvabitch waitlist issue. I've been on it for over two years. I might just quit that list. I hate it. I love it. I love to hate it.

The complication itself doesn't require a large case, but GMT watches tend to arrive with rotating bezels, extra scales, four hands, substantial automatic movements and the general assumption that anyone crossing a time zone also wants 42mm of stainless steel attached to their wrist. Thankfully, that is changing.

While the size of the waitlist gets longer, the size of GMT watches has been gently reducing over the last few years. And there are many options out there, you don't need a Rootbeer, Pepsi, Batman, Bruce Wayne or any crown. Let's turn that frown upside down.

There are now genuinely compact GMT watches from Timex, Seiko, Longines, Tudor and Grand Seiko, alongside a particularly strong group of independent and smaller brands. Some are proper traveller's GMTs with an independently adjustable local-hour hand. Others use the simpler caller-style arrangement, where the GMT hand moves independently. A few are essentially dive watches with another time zone bolted on.

Timex x Seconde Seconde GMT homage collection — These 'Timex x Seconde Seconde' homages were cool, but the hair-puller bracelets are made by the devil himself - oh and they aren't GMTs.

For this guide, the rule is simple: the case must measure less than 40mm. Not 40mm described optimistically as compact. Under 40mm.

That still does not mean every watch here will suit every smaller wrist. Lug-to-lug, thickness, bezel diameter, dial opening and bracelet articulation matter just as much. A 37mm watch stretching 48mm across the wrist can wear substantially larger than a 39mm watch measuring 45mm from lug to lug.

Prices and availability below were checked in October 2026. For brands without both UK and US pricing, the second price is an approximate currency conversion and may not include local VAT, import duty or other charges.

*Nivada currently publishes 42mm on the live product page but 40mm on a separate specifications page. I would use 42mm as the safer figure.

A quick word on caller GMTs and flyer GMTs

A flyer or traveller's GMT lets you jump the main local-hour hand forwards or backwards without stopping the watch. That makes it particularly useful when you actually cross time zones. A caller or office GMT generally allows the 24-hour GMT hand to be adjusted independently instead. That works perfectly well if you mainly want to track another time zone from home. Neither arrangement makes a watch inherently better. But if you travel frequently, the flyer system is noticeably more convenient.

Best GMT watches under £1,000

Q Timex GMT

The Q Timex GMT is the obvious starting point because it manages to look like a proper GMT watch without costing mechanical-GMT money. And it comes without the horrific hair-ripper of a bracelet. The 38mm case is sensible and the approximately 44mm lug-to-lug keeps the overall footprint compact. Timex lists the case at 12.5mm high, so this is not an ultra-thin watch, but the dimensions remain very manageable. The acrylic crystal, rotating 24-hour bezel and retro bracelet put it firmly in the 1970s-inspired Q Timex family.

It uses a quartz movement rather than trying to squeeze an inexpensive automatic GMT calibre into the case. For this price, that is arguably the right decision. You get accurate, low-maintenance timekeeping and a useful second time zone without turning the watch into a thick slab.

The bracelet is where the compromise is most obvious. It suits the design, but it does not have the solidity or refinement of the more expensive watches here. Water resistance is also modest compared with the dive-derived GMTs further down the list.

But at £210, the point is not to compete with Tudor. It is to provide a wearable, recognisable GMT for considerably less than a routine mechanical-watch service.

Best for: the cheapest genuinely compact GMT in the guide.

Glycine Airman No.1 GMT

The Airman is not merely another watch that happens to have a GMT hand. Glycine introduced the original Airman in the 1950s, making the family one of the historically significant early multi-time-zone wristwatches. The current 36mm Airman No.1 GMT is also unusually faithful to those older proportions. Glycine's catalogue specifies a 36mm diameter, 45.5mm lug-to-lug and 11.6mm thickness, with the GL293 automatic movement and a 42-hour power reserve.

That 45.5mm length means it wears somewhat longer than most 36mm watches, but it remains comfortably within compact-watch territory. The thin bezel and relatively open dial also make it look larger than a typical modern 36mm dress watch.

Water resistance is just 30 metres, so despite the military-tool appearance this is not the watch here for swimming holidays. Pricing is also unusually fluid: Glycine's nominal list prices tend to bear little resemblance to the prices actually charged by major retailers. Current examples of the GL0370 are around $749.

That discounting slightly muddies the brand positioning, but it also makes the Airman compelling. Few sub-£1,000 GMT watches have this much genuine history behind the design.

Best for: vintage proportions and actual GMT history.

Lorier Hyperion

The Hyperion is one of the strongest examples of how quickly affordable GMT watches have improved. Its Miyota 9075 movement provides the important bit: an independently adjustable local hour hand. That means proper traveller-GMT functionality at a decent price, something that was considerably harder to find at this price only a few years ago.

The case is 39mm, but the 37mm bezel and 46mm lug-to-lug stop it becoming visually bulky. Lorier gives the steel case as 10.7mm thick before the 1.45mm domed sapphire crystal, giving an overall height of roughly 12.15mm.

There is also 100 metres of water resistance, a screw-down crown, sapphire bezel insert and a bracelet that tapers from 20mm to 16mm. Those dimensions matter. A narrower clasp and articulated bracelet prevent the watch from feeling like a 39mm head attached to an oversized lump of steel.

The Hyperion is currently caught in Lorier's usual pre-order/restock cycle rather than being continuously available. The September 2026 product page lists it at $799 and out of stock while existing pre-orders ship.

Best for: an affordable mechanical traveller's GMT with traditional proportions.

Traska Venturer GMT

The Venturer takes the same Miyota 9075 foundation as the Lorier but approaches the job rather differently. This is a cleaner, more contemporary design, with an internal 24-hour scale operated through the second crown rather than an external GMT bezel. The current watch measures around 38.5mm across, 46mm lug-to-lug and 11.9mm thick, while providing 150 metres of water resistance.

The independently adjustable local-hour hand makes it a genuine flyer GMT, and Traska applies its hardening treatment to the case and bracelet. The brand says this takes the steel to approximately 1,200HV, which is useful on a watch likely to spend time around airport trays, luggage and desks.

At $950 it now sits noticeably above the Lorier, but you get excellent practical specifications and one of the better bracelet/clasp packages in this end of the market.

The 46mm length is also sensible. It has enough footprint to look like a sports watch without stretching towards the edges of a smaller wrist.

Best for: an affordable everyday flyer GMT with strong practical specifications.

Baltic Aquascaphe GMT MK-II

The Aquascaphe GMT MK-II is particularly relevant because it is new for September 2026 and fixes the biggest functional limitation of the previous version. Baltic has switched to the automatic Miyota 9075, turning the Aquascaphe GMT into a true traveller's GMT with an independently adjustable local-hour hand. The new case measures 39.5mm × 47mm × 13.8mm, with 200 metres of water resistance and a bidirectional sapphire 24-hour bezel.

That 13.8mm thickness is worth noting. This is not one of the slimmer options here, although some of that height comes from the double-domed sapphire crystal. The broad bezel also reduces the apparent dial size, so the watch does not look as expansive as many 39.5mm watches.

Pricing starts at €850 on FKM rubber and rises to €915 on either Baltic steel bracelet.

It is one of the better choices if you want the GMT complication in what is effectively a compact dive-watch package rather than a dressier travel watch...if you can deal with the girth.

Best for: traveller-GMT functionality with dive-watch capability below £1,000.

GMT watches around £1,000–£2,000

Christopher Ward C63 Sealander GMT 36

The C63 Sealander GMT 36 is one of the watches that makes this entire guide make sense.

A 36mm case, 43mm lug-to-lug and 11.15mm thickness is properly compact rather than simply smaller than the industry's usual GMT - watch that endlink though! Christopher Ward paired that case with the Sellita SW330-2, 150 metres of water resistance and a 56-hour power reserve.

It is a caller GMT, so the GMT hand adjusts independently rather than the local-hour hand. Whether that matters depends on how you use the watch. For tracking another office, family member or market from home, the arrangement is entirely sensible.

The Light-catcher case also helps. Short lugs, strong case-side bevels and relatively little visual bulk make this wear closer to its stated dimensions than many sports watches.

The problem was availability but the 36mm GMT is back in stock (at time of writing) as part of Christopher Ward's current range.

It gives Rolex Explorer II vibes with the polar dial, bezel and orange GMT hand, but it's different enough to not call it a homage - especially in size. Few mechanical GMTs are genuinely this great while being this compact.

Best for: buyers who want one of the smallest modern Swiss automatic GMT watches.

MAEN Hudson 38 GMT MKII

MAEN's Hudson is one of the more substantially lugged watches here despite its 38mm diameter. The reason is the 47mm lug-to-lug, which gives it considerably more length than the 36mm Farer, Nivada or Christopher Ward. It's not excessive, but it makes the Hudson better suited to buyers who want a smaller diameter without the overall tightness that can come with a genuinely small case.

MAEN specifies the case at 11mm thick excluding its box-domed sapphire crystal, so direct thickness comparisons need care. It houses a Sellita SW330-2 Elaboré movement and offers 300 metres of water resistance, a bidirectional bezel and an on-the-fly bracelet adjustment system. The bracelet options of rubber, jubilee and steel (both with female end link) will all suit a smaller wrist

The GMT hand adjusts independently, making this a caller-style implementation. For some buyers that will make the Miyota 9075 watches more appealing, but the Swiss Sellita calibre remains familiar and serviceable. The combination of 38mm diameter, serious water resistance and a relatively slim metal case is unusual. It is particularly worth considering if you find the 36mm watches here too restrained. However, it might not be for you if you want a splash of colour on the dial - it is a muted, classy affair.

Best for: a compact-diameter GMT that still feels like a substantial sports watch.

Seiko Prospex Alpinist GMT SPB377

Don't you just love an Alpinist. The mechanical Alpinist GMT sits right at the upper edge of our diameter limit: 39.5mm, paired with a much more encouraging 46.4mm lug-to-lug.

It is relatively thick at 13.6mm, but Seiko's case shaping disguises some of that height. And the thick strap helps with the transition to the wrist. The curved sapphire crystal, sloping case sides and internal compass bezel mean the watch does not present itself as one uninterrupted chunk of steel.

Inside is Seiko's 6R54 automatic movement with a 72-hour power reserve. This is a caller-style GMT rather than a traveller's GMT: the 24-hour hand is used to show the second zone. Seiko also gives the watch 200 metres of water resistance and its familiar internal rotating compass ring.

The £1,080 price is harder to ignore. Seiko has moved well beyond the old assumption that an Alpinist should be an inexpensive enthusiast purchase. At this level it faces very capable independent alternatives with better GMT functionality. It's too much for many fans, but there are often deals to be had.

What keeps it relevant is the package. It looks unmistakably like an Alpinist rather than another GMT-Master interpretation, and the sizing is good - it's a classic in its own right.

Best for: Seiko buyers who want an Alpinist first and a GMT second.

Farer Lander IV GMT 36

If compactness is the priority, the Lander IV 36 is difficult to beat. The case measures 36mm across, only 41.2mm lug-to-lug and 11mm thick. Farer even quotes a 38mm pin-to-pin measurement once the strap is fitted, which helps explain why the watch works particularly well on genuinely smaller wrists. It also looks pretty damn good.

Inside is the Top Grade version of Sellita's SW330-2 with a 56-hour reserve. It is a caller GMT, and there is no rotating external 24-hour bezel, so this is not pretending to be a miniature GMT-Master. The additional time-zone scale is integrated into the dial instead.

That helps the proportions. The case remains relatively clean and the 36mm diameter is not swallowed by a thick sports bezel. Farer's sea-green dial also gives the watch a completely different character from the mostly black, blue and steel GMTs in this category.

Water resistance is a useful 100 metres and the redesigned case has a screw-down crown. The watch is currently £1,375 in the UK and $1,575 in the US, with the latest batch now available and in stock. They do a pink dial (Lander Kano) too if you're into that kind of thing.

For those super skinny wrists this is one of the first watches I would look at, they even do short straps as an option. They do a lot of small, great looking watches, but they are a touch expensive, closing in on some entry-level luxury brands. That aside, I must say, thank you Farer for looking out for the skinny wristed.

Best for: genuinely small wrists and buyers who do not want another bezel-heavy GMT.

Lorca Model No.1 GMT

The Lorca is another genuinely compact GMT, although it wears differently from the Farer.

Its main case is 36mm, while the fixed 24-hour bezel measures 37mm. Lug-to-lug is 44mm and total thickness is just 11.2mm including the crystal.

Those are very good dimensions for a mechanical sports GMT. The longer lug-to-lug compared with the Farer gives it slightly more wrist presence, while the small bezel and 19mm bracelet maintain the vintage-influenced proportions.

The Soprod C125 R4 offers a conventional automatic GMT arrangement with independently adjustable GMT hand, a 42-hour reserve and date. Lorca also manages 200 metres of water resistance, which is impressive given the size.

At $1,875, however, this is no longer a value proposition simply because the brand is small. It sits against established Swiss names and several competitors with flyer-GMT movements. The case, bracelet and unusually compact design have to be the reason you buy it.

As of September 2026, Lorca lists the silver dial as in stock while the black version is on pre-order.

Best for: a compact Swiss-made sports GMT with unusually refined proportions.

Nivada Grenchen Antarctic GMT

The Antarctic GMT looks as though someone has taken the dimensions of a vintage watch and resisted the temptation to "modernise" them. It is 36mm across and 11.1mm thick, with a published 42mm lug-to-lug on the live product page. That makes it one of the smallest physical packages here.

The watch uses the Soprod C125, has a 42-hour reserve, acrylic crystal and 50 metres of water resistance. The independently adjustable GMT hand makes it a caller-style system.

Its appeal is therefore mostly about proportion and character rather than outright specification. Acrylic at this price will divide opinion, and 50 metres of water resistance is modest beside the Lorca, MAEN or Baltic.

But very few modern automatic GMTs combine a 36mm diameter with this much period-correct visual character.

Best for: vintage-style sizing without buying an actual vintage GMT.

Serica 8315 GMT Chronomètre

The Serica 8315 is one of the more original watches in a category where originality is not always abundant. Rather than copying the conventional 24-hour bezel layout, Serica uses two 12-hour scales with a day/night indication. The lollipop GMT hand then works with that display to distinguish the second time zone. It takes a little more familiarisation, but it gives the watch its own identity. The case is 39mm × 46.5mm × 12.3mm, with 200 metres of water resistance. Inside is a COSC-certified Soprod C125 automatic caller-GMT movement.

Those dimensions are very well judged. A 46.5mm length is short enough for many smaller wrists, while 39mm stops the unusual dial and bezel arrangement becoming cramped.

There is also more specification here than the vintage appearance suggests: sapphire crystal, ceramic bezel and serious water resistance. The large crown and visually complex bezel do give it more presence than the dimensions suggest.

The downside is price. At around £1,800 it is expensive, for those who are after it, the lack of flyer functionality becomes a legitimate consideration. Saying that, the unique design and original take on the GMT is very welcome and it has great specs and looks, love the bracelet and case details - not sure about those squinty hour markers though... One for the contrarians maybe!

Best for: buyers who want a compact GMT that does not look like everyone else's.

Premium GMT watches for smaller wrists £2000 +

Longines Spirit Zulu Time 39

The 39mm Spirit Zulu Time is one of the easiest premium GMTs to recommend on dimensions alone. Longines took a watch that originally arrived at 42mm and reduced it to 39mm, without making it look undersized or forcing the dial furniture together. The case is approximately 46.7mm lug-to-lug and 13.5mm thick.

Inside is the L844.4 automatic movement, with an independently adjustable local-hour hand, approximately 72 hours of power reserve and COSC chronometer certification. Longines also gives the watch a bidirectional ceramic bezel and 100 metres of water resistance.

It is not especially thin, but the moderate lug length matters more on a smaller wrist. The lugs do not extend dramatically beyond the case and the bezel keeps the dial opening under control.

At £2,950/$3,550 it also occupies a useful position between the enthusiast brands and Tudor/Grand Seiko. It has the lot. The only real question is visual taste. The oversized Arabic numerals, five stars and substantial crown give the Spirit a busier, more overtly modern appearance that might not suit all.

Best for: a mainstream Swiss traveller's GMT with very sensible dimensions.

Grand Seiko SBGN029

Firstly, let us not dismiss the SBGN029 because it's quartz. Grand Seiko's 9F86 is exactly the kind of movement that makes quartz interesting. It is rated to around ±10 seconds per year, has an independently adjustable local-hour hand and retains the instant practicality that makes quartz particularly well suited to a travel watch.

The case is also excellent for this guide: 39mm wide, 45.9mm lug-to-lug and 12.3mm thick. Those figures are unusually compact for a 200-metre sports GMT.

The relatively short 45.9mm length is the key. It is shorter across the wrist than the Tudor, Longines, Baltic, MAEN and several much cheaper watches here.

Grand Seiko's finishing is also part of the appeal. The sharply defined case surfaces, applied indices and highly legible dial make it feel much more expensive than the word “quartz” tends to suggest to anyone who stopped paying attention after buying a £20 digital watch.

At £3,300 it's not cheap, nor is it trying to be. This is effectively Grand Seiko's high-accuracy quartz hero in a compact, highly capable sports-watch case.

Best for: accuracy, compact dimensions and buyers who value function more than mechanical orthodoxy.

Tudor Black Bay 58 GMT

The Black Bay 58 GMT is the watch many people were waiting for after Tudor's original 41mm Black Bay GMT proved rather substantial. The 58 GMT comes in at 39mm × 47.8mm × 12.8mm, giving it almost the same basic footprint as the standard Black Bay 58 while adding a date, 24-hour bezel and full GMT movement.

That movement is the MT5450-U, an integrated flyer GMT with an independently adjustable local-hour hand, roughly 65 hours of reserve, COSC certification and METAS Master Chronometer certification. The case remains water-resistant to 200 metres.

The lug-to-lug is not the shortest here. At 47.8mm, this is towards the larger end of our supposedly small GMT collection. But the curved case profile, 20mm bracelet and relatively restrained 39mm diameter make it substantially easier to wear than the older full-size Tudor GMT.

There is now a five-link bracelet option, but the three-link reference used here remains £4,310 in the UK and $5,525 in the US. It is expensive, but there is very little technical compromise: proper traveller-GMT functionality, strong water resistance, chronometer testing and dimensions that work on wrists previously excluded from much of the luxury GMT market.

Best for: a compact luxury mechanical GMT that can also serve as an everyday sports watch.

SUPER OBVIOUS WILD CARD

Rolex GMT Master II 126710BLNR

You knew this would happen, I just couldn't let it go. My justification is that the Tudor at 39mm is almost 48mm lug to lug, and the Pepsi et al, are 40mm and 48mm lug-to-lug. And it's one of the most iconic watches ever made. I found that the GMT Master II and the Daytona, at 40mm, fit surprisingly well on the skinny wrist. The Daytona hugs so nicely.

The Rolex GMT-Master II 126710BLNR does not technically qualify for this guide. Rolex lists the case at exactly 40mm, and the rule here is under 40mm. It gets a wildcard entry because it's the king of GMT watches, and I like it a lot. The dimensions are just about doable for those shopping for a GMT for a smaller wrist.

The blue-and-red Cerachrom bezel gives the Pespi its familiar appearance, while the calibre 3285 provides a proper traveller's GMT system with an independently adjustable local-hour hand, approximately 70 hours of power reserve and Rolex's Superlative Chronometer specification of -2/+2 seconds per day after casing. Water resistance is 100 metres. Of course there are other colours that are still in production, so you can pay a mark up or join the waitlist- oh joy.

The important figures here are the ones Rolex does not publish. Independent measurements put the current case at roughly 48mm lug-to-lug and around 12mm thick. That is reasonably compact for a modern luxury GMT, but the broad lugs and the end links on the osyter bracelet make it look and feel larger than 40mm. Which means, bracelet choice also matters. The Jubilee version articulates very well and can help the watch settle onto a smaller wrist, while the Oyster gives it a more conventional sports-watch appearance. And if those fail, maybe a nice oysterflex style rubber strap will make it fit like a glove.

The larger problem is price and availability rather than size. Current UK retail for steel GMT-Master II models sits around £9,850–£10,050, with US pricing around $11,800–$12,000, depending on bracelet and configuration. Rolex continues to sell the non-Pepsi BLNRs, although buying one from an authorised dealer is a separate matter from it technically being in production. The Pepsi is of course discontinued, which is heartbreaking for me, having been on the list for two years and then being abandoned by Rolex. It's an absolute shocker, I was devastated. I still am.

Anyway, for wrists around 6.5 inches and above, it is absolutely worth trying. On smaller wrists it becomes more subjective, particularly because the wide case and bezel create more visual mass than several watches in the main list.

It misses our cut-off by precisely one millimetre. In practical terms, though, the GMT-Master II remains compact enough to deserve consideration alongside the larger-wearing 39mm watches here.

Best for: buyers who want the benchmark modern luxury GMT and can tolerate one millimetre of rule-breaking.

So which compact GMT should you buy?

The answer changes rather dramatically with budget. At the affordable end, the Q Timex GMT is hard to object to. It is compact, inexpensive and does the job without pretending that a cheap mechanical movement would automatically make it better.

Around the £600–£1,000 mark, the choice becomes much more interesting. The Lorier Hyperion, Traska Venturer and new Baltic Aquascaphe GMT MK-II all offer Miyota 9075 traveller-GMT movements. The Lorier is the most traditionally styled, the Traska the cleaner everyday option and the Baltic the obvious choice if you want dive-watch capability.

For genuinely small wrists, the field changes. The Farer Lander IV 36, Nivada Antarctic GMT, Lorca Model No.1 and Christopher Ward C63 Sealander GMT 36 all prove that a mechanical GMT does not need a 39–40mm case. Of those, the Farer's 41.2mm lug-to-lug makes it especially convincing where wrist space is limited.

The Longines Spirit Zulu Time 39 is probably the clearest step into mainstream Swiss luxury, with a proper traveller's movement and very well judged proportions.

The Grand Seiko SBGN029 is the rationalist's choice. It is shorter across the wrist than most of the mechanical watches here, brutally accurate and almost absurdly practical for travelling. And at the top of the list, the Tudor Black Bay 58 GMT finally provides what Tudor enthusiasts had been asking for: a full mechanical GMT without the dimensions of the original Black Bay GMT.

There is no need to buy the smallest watch in this guide simply because your wrist is small. A 39mm GMT with short, curved lugs can work perfectly well. The point is to look beyond diameter. A watch measuring 39 × 48mm and another measuring 39 × 45.9mm may sound nearly identical until you put them on a 6.25-inch wrist.

What to look for when buying a GMT for a smaller wrist

Lug-to-lug matters first. Below about 46mm is a useful starting point for genuinely smaller wrists, although wrist shape matters as much as circumference.

Do not ignore thickness. GMT movements and rotating bezels add height. Anything around 11–12mm is impressively slim for a mechanical GMT; 13–14mm can still work if the case and crystal distribute the height intelligently.

Look at the dial opening. A 39mm dive-style GMT with a broad bezel can look considerably smaller than a 39mm watch with a thin fixed bezel and expansive dial.

Check the bracelet end links. Male end links can extend the effective length beyond the published lug-to-lug measurement. Fully articulating female end links generally help smaller wrists.

Decide whether you actually need a flyer GMT. If you regularly change local time when travelling, it is worth having. If you spend most of your time tracking a colleague or family member overseas, a caller GMT is entirely adequate and may open up better watches for the money.

Final thoughts

Compact GMT watches are finally becoming a category rather than a collection of exceptions. Farer, Nivada Grenchen and Baltic lead the way in this regard with multiple smaller watches in their wider stables. It's a been a joy exploring this niche, I was so hung up on that Rolex GMT Master II that I couldn't see forest for that GMT. There are some superb options, the kooky Serica, the Nivada Grenchen, Lorier and the Farer stood out to me.

More importantly, buyers no longer have to choose between small dimensions and worthwhile specifications. There are 36mm automatic GMTs, sub-£1,000 flyer GMTs, 200-metre travel watches and premium Swiss options below 40mm. The best development is not any single watch on this list. It's the range.

A few years ago, someone wanting a serious GMT on a six-inch wrist had remarkably few sensible choices. Now the problem is deciding between them. And the price, it's tough to get a decent microbrand piece for less that £1000 these days, so once you've bought the watch you'll have to save up for the ticket abroad that allows you to use the GMT function. Pros and cons as I always say, at least us skinny-wristed folk can enjoy a well-sized dual time as we travel from the sofa to the kitchen.

Yours Dualtimingly,
