Short answer: most people wear a watch on the wrist they don't write with. If you're right-handed, that's your left wrist. If you're left-handed, either wrist is fine, and plenty of lefties wear it on the right. It should sit just above the wrist bone, snug enough that it doesn't spin, with room to slide one finger underneath.
That's the whole rule. Here's the reasoning behind it, so you can decide what works for you.
Why most people wear a watch on the left wrist
There's no law about it, but the habit exists for practical reasons:
- It stays out of the way. Your dominant hand does most of the work: writing, carrying, opening doors. A watch on the other wrist takes fewer knocks and scratches.
- The crown doesn't dig in. On most watches the crown (the little knob you use to set the time) sits at 3 o'clock. On the left wrist it points toward your hand and away from the back of your wrist, so it doesn't press into your skin when you bend your hand.
- You can check the time mid-task. You can glance at your left wrist while your right hand is still writing, holding a phone or steering.
- Old habits. Mechanical watches used to need winding every day, and it's easier to turn a crown with your dominant hand while the watch is on the other wrist.
What if you're left-handed?
Wear it wherever it feels right. Many left-handed people wear their watch on the right wrist for the same reasons right-handed people wear it on the left. Some wear it on the left anyway because that's how they learned. The only real downside on the right wrist is that the crown can face your hand and press against it when you bend your wrist back. If that bothers you, a slightly looser fit usually fixes it.
Can you wear a watch on your dominant wrist?
Yes. Some people find it more comfortable, some like the look, and some just prefer it. Expect a few more bumps against desks and door frames, and choose a watch with a sturdy crystal and decent water resistance if your dominant hand is busy all day.
Where on the wrist should a watch sit?
Find the small round bone on the outside of your wrist, on the pinky side. For most people, the watch looks and feels best just above that bone, toward the elbow. There it doesn't slide down onto your hand, and it isn't pressed by the bone every time you move.
Some people prefer it just below the bone, closer to the hand, especially with a smaller dress watch. That works too. Pick one spot and size the strap for it. A watch that keeps drifting over the bone is the one that feels uncomfortable.
With a dress shirt: the cuff should cover part of the watch or sit right at its edge when your arms are at your sides. That's one reason slim watches are popular for work. A case around 10mm thick slides under a cuff. Many chronographs are 13 to 15mm thick and get caught on it.
How tight should a watch be?
Use the one-finger rule: with the watch on, you should be able to slide one finger (not two) between the strap and your wrist. That's snug enough that the watch stays in place on top of the wrist, and loose enough that your skin can breathe.
It's too loose if:
- the watch spins so the dial ends up on the inside of your wrist
- it slides down onto your hand when you lower your arm
- it rattles or slaps when you walk
It's too tight if:
- it leaves a deep red mark or a pattern on your skin
- your hand tingles, or you keep wanting to take it off
- the strap creases sharply where it bends
Adjust for the season and time of day. Wrists swell a little in hot weather, after exercise and later in the day. If a watch fits perfectly in the morning and feels tight by evening, go up one strap hole or loosen the bracelet slightly.
Leather strap vs. steel bracelet fit
- Leather strap: easy to adjust, one hole at a time. New leather is stiff and loosens a little as it breaks in, so it's fine if it feels slightly firm for the first week.
- Steel bracelet: sized by removing links. Any watch shop or jeweler can do it in a few minutes. If you land between sizes, err slightly loose rather than tight. A metal bracelet doesn't stretch.

Quick answers
Is it wrong to wear a watch on your right wrist?
No. It's a habit, not a rule. Wear it where it's comfortable and where you'll actually look at it.
Should a watch go over or under the wrist bone?
Most people wear it just above the bone, toward the elbow. Just below the bone also works for smaller watches. Directly on the bone is usually the least comfortable spot.
How do I know if my watch is too big for my wrist?
Look at the lugs, the parts where the strap attaches. If they hang past the edges of your wrist, the watch is too big. For most wrists, a case around 38 to 40mm with a lug-to-lug of 45 to 46mm sits right.
Should you sleep with a watch on?
You can, but most people take it off. It gives your skin a break and keeps the strap from wearing out faster.
A watch that fits most wrists
Both Season watches are 39mm with a 20mm strap or bracelet, the size that sits right on most wrists. Season No. 1 is 9.8mm thin with a 45mm lug-to-lug, so it slides under a shirt cuff, on a leather strap, for $149. Season No. 2 is a 39mm mecaquartz chronograph with a 46mm lug-to-lug on a steel bracelet, 10 ATM water resistant, limited to 100 pieces per color, for $199. Shipping is free, and every order includes a free Autism Awareness watch while stock lasts.
