These Are the 20 Best Small Men’s Watches Under 40mm

A watch should be framed by your wrist, not enveloped by it.


There’s been much written about the “sweet spot” for watch sizes. Ten years ago, the conventional wisdom skewed between 40mm and 42mm. Today, things have widened a bit, to include watches down to around 38mm. Why the drop in millimeters?

I’d argue it’s largely about comfort. You see, the way a watch sits on the wrist is hugely affected by its diameter, which is mostly what we mean when we refer to a watch’s size. But there’s more going on here: the way a watch wears has just as much to do with its thickness, also measured in millimeters; and its lug-to-lug length, literally measuring from the tip of one set of lug to the other, has much to do with whether you want to take it off at the end of the day or sleep in it. And, generally, a watch with a smaller diameter width will also be slimmer, and have a shorter lug-to-lug length.

There are exceptions, of course. But they don’t sway me, personally. I have what you’d call average-sized wrists, and I wear a 35.5mm vintage Zodiac Sea Wolf every day. It’s great. The crown doesn’t dig into my hand, and, when I camp, I wear it to sleep, no problem. Here’s the other side of things, the one I think a lot of guys think about but don’t mention, when they talk about why they don’t wear small watches: No one has ever seen this watch, taken it into their hands, and said, “But it’s so small!” Men wore them this small throughout the middle of the 20th century, and I’m not buying that we’ve “moved on” from that size. Fashion is cyclical, after all.

The truth, I believe, is that any size between 35mm and 38mm offers plenty of size of legibility and simply looks good, even on a larger wrist. But don’t take my word for it. Try on any of these watches, all under 38mm in diameter, and you’ll see that a small watch might just be the best watch.

Seiko 5

The Seiko 5 is as ubiquitous as it gets: it comes in all sizes, shapes, and colors. This means you can find many of its iterations in case sizes below — and sometimes well below — 38mm.

Timex Marlin

Timex’s Marlin is a hell of a great watch to have around: it’s mid-century on a budget, available in a number of great colors (the silver dial is our favorite, especially on mesh), and, particularly for those with smaller wrists, it’s a great dressy watch to match with all sorts of looks.

MKII Hawkinge

Philadelphia-based MKII is a maker of much-sought-after homage watches. This one is inspired by the JLC and IWC MK 11, made for the British military between the 1940s and 1980s. This is actually MKII’s second version of the watch—Bill Yao shrank it from 40mm to just under 38mm to make it more wearable. And wait time (because you should be wondering) is just three weeks.

The original Oris Divers Sixty-Five is a darling of the watch nerd community: the look, the price, the brand, are all near perfect. In 2018 they released a 36mm size, which is candy for smaller-wristed dive watch fans. They’ve got it in eight different configurations, all just as ready to be worn into the ocean — and even more suited under the jacket cuff — as the 40mm version.

Tudor Black Bay 36

The Tudor Black Bay dive watch, while sharp, clocks in at a chunky 41mm and almost 15mm of thickness (though the Tudor Black Bay 58, which is basically unobtanium, is smaller). Which is why Tudor (and Rolex) fans rejoiced in 2016, when Tudor released the Black Bay 36mm, which looks a lot like a modernized Rolex Explorer. How cool is it? Lady Gaga reps the damn thing.

Grand Seiko SBGR 251

You can point out that it’s pretty chunky (can one call a watch “phat”?) at 13.3mm thick. But this is about as small as Grand Seiko gets, and you can imagine all the mechanical magic they pack into its 37mm case.

Rolex Oyster Perpetual 34

Folks in the know view vintage Oyster Precision models from the 1950s — and their 34mm diameter — as the ultimate value play. So why would you ignore the modern equivalent? That’s not the 36mm version of the Oyster Perpetual — it’s the 34mm.

IWC Pilot’s Automatic 36mm

As Jason Heaton noted back in 2016, the launch of the Pilot’s Automatic 36mm was the most genuine pilot’s watch from IWC in a while — for the first time, the dimensions of the watch were not blown up to a modern-sized 40mm. Instead, they stayed closer to the original. The result is a watch that your grandpa really would’ve worn.
Case Size: 36mm
Thickness: 10.7mm
Movement: IWC 35111 automatic
Price: $5,150

Jaeger-LeCoultre Reverso Classic Small
