To size a watch bracelet, you remove links until the watch stays in place on your wrist with room for one fingertip under the clasp, then use the clasp's small adjustment for the final fit. Take links from both sides of the clasp so that it stays centered under your wrist, and keep every link you remove. Most steel bracelets can be sized in ten minutes with the right tool; if the links are held by screws or you are unsure, a watchmaker will do it for very little.
A bracelet that fits well makes more difference to comfort than almost anything else about a watch. This guide explains how the fit should feel, how bracelets come apart, and what the adjustment systems on modern watches do.
How a bracelet should fit
- The watch should not slide. It should stay on top of your wrist and not rotate to the side when you move your arm.
- It should not leave a deep mark. A faint impression after a day is normal; a red band is too tight.
- The one-finger test. You should be able to slip the tip of a finger under the clasp, and not much more.
Remember that your wrist changes size. It swells in heat and after exercise and shrinks in the cold, by enough to be felt. Size the bracelet when your wrist is at its normal, warm size, and rely on the clasp adjustment for the rest.
How to work out how many links to remove
- Put the watch on and close the clasp.
- Pinch the slack together at the clasp and count how many links are gathered.
- That is roughly the number to remove.
Take links from both sides of the clasp, not all from one. The aim is for the clasp to sit in the middle of the underside of your wrist, so the watch head sits in the middle of the top. If you have to remove an odd number, take the extra one from the side at 6 o'clock; most people find that keeps the watch from sliding toward the outside of the wrist.
How to size a watch bracelet: the three kinds of link
Look at the side of the bracelet near the clasp. The removable links are held together in one of three ways.
Screws
Rolex, Tudor, Omega on most current models, and many other makers use small screws. You can see the slot of the screw head on one side of the link.
- Use a screwdriver that fits the slot exactly. One that is too small will chew up the head.
- Work over a towel or tray, so that a dropped screw does not vanish.
- Some makers put thread-locking compound on the screws. If a screw will not move, do not force it: gentle heat from a hair dryer softens the compound, or take it to a watchmaker.
- When you reassemble, tighten firmly but do not overtighten.
Push pins
Many less expensive watches use friction pins. Small arrows on the inside of the links show the direction in which the pin is pushed out.
- A simple bracelet tool with a threaded pusher does the job.
- Push in the direction of the arrow. Put the pin back from the opposite side.
Pin and collar
Seiko and some other makers use a pin with a tiny separate sleeve, the collar, that grips it. The collar is easy to lose and the bracelet will not hold without it. If you see a small tube fall out when you remove a pin, keep it and put it back in the same place. Many owners leave this type to a watchmaker.
The clasp: micro-adjustment
Links are a coarse adjustment. The clasp does the fine one.
Adjustment holes. Many clasps have a row of small holes along the side. The end of the bracelet is held by a spring bar that can be moved from one hole to the next, each a couple of millimeters apart. Push the bar in with a pointed tool, slide it along and let it snap into the next hole.
Half links. Some bracelets include one or two shorter links, so you can adjust by half a step.
Tool-free extensions. Modern sports watches increasingly let you adjust the length while the watch is on your wrist:
- Rolex Easylink folds out a link inside the clasp to add about 5 mm. Rolex Glidelock, on dive watches, slides in small steps to a total of about 20 mm.
- Tudor T-fit slides through several positions for a total of about 8 mm.
- Omega fits many Seamaster and Speedmaster clasps with a push-button adjustment, and dive models with an extension for wearing over a wetsuit.
- Cartier SmartLink, on the Santos, releases each link with a small button, so the bracelet can be sized without tools at all.
If your watch has one of these, size the bracelet with the extension closed, slightly on the snug side. Then you can open it on a hot day.
Integrated bracelets
Watches with an integrated bracelet, such as the Tissot PRX or the Cartier Santos, need more care. The bracelet tapers, the links are different widths, and many have a butterfly clasp with no adjustment holes at all. The fit depends entirely on the number of links, sometimes with a half link to help. It is worth getting these sized by someone who has done it before.
Mesh bracelets
A mesh bracelet, as on some Breitling and Omega models, has no removable links. It is shortened by sliding the clasp along the mesh and locking it, or, on some designs, by removing short sections near the clasp. Follow the maker's instructions for that model.
When to leave it to a watchmaker
Sizing a bracelet is simple, and a slip can leave a permanent scratch. Go to a watchmaker if:
- The screws are tight or have thread-locking compound.
- The bracelet is gold or has polished surfaces that mark easily.
- It uses pins and collars.
- The watch is valuable and you would rather not practice on it.
It usually takes a few minutes.
Keep the spare links
Put every removed link, screw and pin in a small bag and keep it with the box. A watch with all its links fits more buyers and is worth more when you sell or trade it in. Replacing missing links from the maker is expensive, and for older models it can be difficult.
When you buy a pre-owned watch, ask how many links are fitted and what wrist size it fits. We answer that for any watch on our site before you buy, and every listing states whether the box and papers are included. Our guide to what a full set means lists what should come with a watch.

Frequently asked questions
How tight should a watch bracelet be?
Snug enough that the watch does not slide or rotate, with room to slip the tip of one finger under the clasp.
How many links should I remove from each side?
About the same from each side of the clasp, so the clasp stays centered under your wrist. With an odd number, take the extra link from the 6 o'clock side.
Can I size a Rolex bracelet myself?
Yes, with a screwdriver that fits the link screws exactly. If a screw will not turn, stop and take it to a watchmaker, since the screws are sometimes secured with thread-locking compound.
What is micro-adjustment on a watch clasp?
A fine adjustment in the clasp, either a row of holes for the spring bar or a sliding extension, that changes the length by a few millimeters without removing links.
Should I keep the links I remove?
Yes. Spare links let you resize the watch later and add to its value when you sell.
Will you tell me if a watch fits before I buy?
Yes. Tell us your wrist size and we will check the number of links on the watch. Every watch is checked by our specialist before it ships.
