Why 38mm Watches Are Having a Moment in 2026

For years, bigger was seemingly better in the watch world. Cases grew, sports watches became chunkier and anything below 40mm was often dismissed as being on the small side.

In 2026, things look very different.

Collectors are increasingly embracing smaller, more wearable watches, and one of the clearest signs yet arrived in August with the latest generation of the Omega Speedmaster 38.

Omega has refreshed the collection with seven new models, combining its existing 38mm proportions with styling that moves much closer to the iconic Speedmaster Moonwatch. citeturn289600search0turn368562search2

So, has 38mm become the new sweet spot?

The new Omega Speedmaster 38 makes the case

The Speedmaster 38 isn’t technically a brand-new model, but Omega’s 2026 update feels significant.

Gone are the oval subdials of the previous generation. In their place are traditional round subdials, a cleaner dial layout and a more substantial Moonwatch-style bezel complete with the famous Dot Over Ninety detail.

The stainless-steel black-dial model measures 38mm across, 44.96mm lug-to-lug and offers 100 metres of water resistance. Inside is Omega’s automatic Co-Axial Calibre 3332, delivering a 52-hour power reserve. citeturn368562search2

It is still unmistakably a Speedmaster, but the new design gives collectors something many have wanted for years: the feel of the classic Speedmaster aesthetic in a considerably more compact package.

And Omega isn’t alone.

Smaller watches have been creeping back for years

The return to smaller dimensions hasn’t happened overnight.

Vintage-inspired watches, compact dive watches and traditional dress watches have all helped shift tastes away from the oversized cases that dominated much of the 2000s and early 2010s.

At Watches & Wonders 2026, smaller proportions sat alongside another growing theme: brands revisiting established designs rather than simply making watches larger or more complicated.

The result is a market where 36mm, 37mm, 38mm and 39mm watches no longer feel like niche alternatives. For plenty of buyers, they’re now the preferred choice.

The new Speedmaster 38 simply puts one of the industry’s biggest names behind the movement.

Why does 38mm work so well?

Watch measurements rarely tell the whole story.

A 38mm watch with long lugs can wear larger than a compact 40mm model, while bezel thickness, bracelet design and case shape all influence how a watch feels on the wrist.

But 38mm sits in an interesting middle ground.

It’s large enough to retain the presence expected from a modern sports watch, while being compact enough to work across a wide range of wrist sizes.

It also makes a watch easier to wear.

A slightly smaller case is less likely to catch on a shirt cuff, can feel more balanced during everyday use and often gives vintage-inspired designs more authentic proportions.

The appeal isn’t necessarily about watches becoming “small”. It’s about wearability becoming more important than diameter alone.

The return of versatility

Collectors are also becoming less interested in rigid categories.

A dive watch doesn’t have to be enormous. A chronograph doesn’t need to dominate the wrist. And a 36mm watch isn’t automatically a dress watch.

That versatility makes compact watches particularly attractive to collectors who want fewer watches capable of doing more.

A well-proportioned 38mm sports watch can work with a T-shirt, office wear or something smarter without feeling out of place.

For many buyers, that matters far more than having the biggest case possible.

Does this mean large watches are finished?

Not at all.

There will always be demand for 42mm, 44mm and larger watches, particularly within professional dive watches, aviation watches and more technical designs.

Watch size is ultimately personal.

What has changed is the idea that a men’s watch needs to start at 40mm.

Collectors now have far more freedom to choose a watch based on how it actually looks and feels on the wrist rather than worrying about whether the number on the specification sheet is big enough.

Is 38mm the perfect watch size?

There isn’t one perfect size for everybody.

But 38mm is increasingly looking like one of the most versatile.

The latest Omega Speedmaster 38 is another major vote of confidence in compact watches and, with collectors continuing to embrace more traditional proportions, we’re expecting plenty more brands to follow.

If you’ve always overlooked smaller watches, 2026 might be the year to try one on.
