Shortening a metal watch bracelet (steel, Milanese, Jubilee, Oyster) requires a pin punch kit and a good read of the links. A well-fitted bracelet lets a flat finger pass between the skin and the metal: neither tight nor loose. Here is the seven-step method to break nothing.

Required kit
A basic kit costing €15 is enough for 95 % of bracelets:
- Pin punches 0.8 / 1.0 / 1.2 mm in hardened steel.
- Plastic bracelet holder with grooves.
- Watchmaker mallet 30 to 50 g.
- Brass tweezers to grip the pins without scratching.
- 1.4 mm screwdriver flat or Phillips for screwed pins.
Identifying removable links
Turn the bracelet over: the removable links show engraved arrows indicating the punch direction. The fixed links (usually the two clasp end-pieces and the central watchmaker's link) bear no arrow. Count the number of links to remove: as many on the 6 o'clock side as on the 12 o'clock side to keep the clasp centred.
Split, screwed or clipped pin?
| Type | Visual clues | Tool | Direction |
|---|---|---|---|
| Split pin | Fine slit on the side face | Punch 0.8-1.0 mm | Follow the arrow |
| Solid pin + collar | Small visible brass cylinder | Punch 1.0 mm then tweezers | Follow the arrow |
| Screwed pin (Tudor, Rolex) | Slotted or hex head | 1.4 mm screwdriver | Unscrew flat |
| Clipped Milanese | Folded tab | Fine screwdriver | Lift then pull |
Seven-step removal
- Lay the bracelet on the holder, arrows facing down.
- Place the 1.0 mm punch at the hole entry marked by the arrow.
- Strike 3 to 5 sharp blows with the mallet until the pin sticks out by 4 mm.
- Grip the pin with the brass tweezers and pull it along its axis.
- Separate the link: it slides off sideways.
- Repeat identically on the opposite side of the clasp to keep balance.
- Reassemble by reinserting the pins in the reverse direction of the arrows, until flush.
Always reinsert the pin against the extraction direction: the catch flats face outwards and the bracelet locks mechanically.

Keeping the clasp balanced
If you remove 4 links, that means 2 + 2, never 4 + 0. On bracelets with a centred deployant clasp (Oyster, Jubilee), the offset quickly becomes visible and uncomfortable. If the number of links to remove is odd, take (n-1)/2 from one side and (n+1)/2 from the other: the eye tolerates only one link of difference.
FAQ
How many links should I remove?
Measure your wrist, add 1.5 cm for skin breathing. Subtract from the total bracelet length: divide by the width of one link (typically 8 to 10 mm) to get the number.
What if the pin refuses to come out?
Check the direction (arrow) and increase the punch diameter by 0.2 mm. If nothing works, apply a drop of WD-40 and wait 5 min: internal corrosion will release.
Lost a pin: what to do?
Buy a universal assortment (200 pins, €5): you will certainly find the right diameter. Measure the old one before replacement.
Can I shorten a Milanese bracelet?
Yes, by unclipping the clasp and cutting with a 32-tooth hacksaw; a more delicate operation that deserves a workshop.
