What Case Size Should You Wear? A Deep Dive into Watch Proportions
We at The Wind Up spend a lot of time on microbrands, neat straps, enamel dials and indie storylines. But every now and again, the big question comes up: what size really suits me? Watch case size isn’t just about numbers. It’s about comfort, proportion, style, how it feels under your cuff, how it balances with your wrist and build.
Let’s explore the common size groups, their strengths and drawbacks, and match each one with a watch that embodies it.

36mm and Under — The Elegant Throwback
The classic vintage size. Elegant, slim, and wonderfully discreet. These watches tuck under a shirt cuff without fuss and carry decades of heritage. The trade-off is wrist presence: on larger wrists, they can feel lost, and legibility suffers if you want bold markers or complications.
Pick: Tudor Black Bay 36
It’s everything people love about Tudor’s dive-inspired design, shrunk into a dressy, wearable package. The 36 wears beautifully, has a rugged build, and shows that small watches can still pack presence.

37–40mm — The Modern Sweet Spot
The sweet spot for many modern buyers. Enough presence without tipping into bulky, versatile enough for everything from office wear to casual weekends. It’s also the size range most brands pour their effort into, so the choice is huge. If there’s a drawback, it’s that smaller wrists can still find them hefty, and some sport designs feel toned down at this diameter.
Pick: Omega Aqua Terra 38mm
The Aqua Terra 38 has one of the most versatile profiles in watchmaking. Elegant enough for a suit, tough enough for the weekend, and endlessly comfortable thanks to its slim case. This is the definition of “wear-anywhere” modern sizing.

41–44mm — The Statement Zone
Dive watches, pilot watches, sport chronographs—all thrive here. Bigger dials mean better legibility, stronger wrist presence, and that undeniable sense of toughness. On the downside, these can feel heavy over a long day and will often struggle to fit neatly under a shirt cuff.
Pick: Breitling Superocean 42
Breitling’s modern diver nails the category: chunky, bright, highly legible, and confident on the wrist. At 42mm it’s a presence piece without sliding into parody, making it a strong example of why this size range works for tool watches.

45mm and Above — Is There “Too Big“?
Big, bold, and unapologetic. Perfect for oversized tool watches, experimental cases, or those who want to make an impact at a glance. But for daily wear? They’re demanding. Comfort is harder to maintain, weight is noticeable, and unless you’ve got the wrist to match, they risk looking more novelty than necessity.
Pick: Panerai Submersible 47mm
The Panerai Submersible is unapologetically large, proudly bold, and practically built to be a wrist anchor. It thrives on size, and while it’s not for everyone, it’s the ultimate demonstration of how 45mm+ watches carve their own lane.
Final Thought
If you’re a slightly overweight 42-year-old, beard-wielding business owner, the safe money is on the 40mm zone. Big enough to show character, restrained enough to stay comfortable day in and day out, and versatile enough to swing between the office, the pub, and a weekend away. It’s the Goldilocks choice—bold without being brash, practical without being boring.
