A watch is chosen first and foremost for its style, but it looks and feels better at the right size. Two measurements matter: the case diameter, which should suit your wrist, and the length of the strap or bracelet, which can almost always be adjusted. Here is how to measure your wrist, choose your dial and get the fit just right.
Measuring your wrist
Wrap a soft tape measure around your wrist, just above the wrist bone, where you wear your watch. Pull it snug without squeezing. If you don't have a tape measure, use a strip of paper: mark where the ends meet, then lay the strip flat and measure it with a ruler.
Men's wrists usually measure between 16 and 20 cm around. Keep this measurement in mind: it will help you choose the dial diameter and check the length of the strap or bracelet.
Choosing the dial size
The diameter is measured from one edge of the case to the other, not counting the crown, the button used to set the time. It is given in millimetres on the product page when it is known. A few pointers:
- Slim wrist (under 17 cm): a case of about 36 to 40 mm looks balanced and slips under a shirt cuff.
- Medium wrist (17 to 19 cm): 40 to 44 mm, the most versatile size.
- Large wrist (over 19 cm): a case of 44 mm or more, for a watch that really stands out.
Think about thickness too: a dress watch is meant to be slim so it slips under a cuff, while a sports or automatic watch is often thicker. The lugs, which attach the strap or bracelet on either side of the case, should not extend beyond the width of your wrist.
Adjusting the strap or bracelet
Leather, silicone or fabric strap
It fastens with a pin buckle, whose prong slots into one of the holes. The watch fits well when you can slide a finger between the strap and your wrist. Avoid punching an extra hole until you have decided to keep the watch.
Link bracelet
A metal bracelet is shortened by removing links, on both sides of the clasp to keep the dial nicely centred. The links are held in place by small pins or screws: a jeweller, a watchmaker or a shoe repair shop can remove them in a few minutes. You can also do it yourself with a suitable tool known as a pin pusher. Keep the links you remove: you will need them if you want to lengthen the bracelet or return the watch.
Mesh strap
A mesh strap is a fine, supple weave of metal. Its clasp usually slides along the strap and locks at the length you want: a simple adjustment you can make yourself, with no tools.
How to wear your watch
A watch is usually worn on the wrist opposite your writing hand, just above the wrist bone. When properly adjusted, it doesn't slide down towards your hand or leave a mark on your skin. In hot weather or during exercise, your wrist swells slightly, so leave a little room.
