Hamilton's steel bracelets use pins, not screws. The Jazzmaster and the older Khaki Pilot Day Date use pin and collar, the Khaki Aviation Pilot uses push pins. Reviewers even complain about it: one wished Hamilton had used screws instead of push pins. For you, it means a pin pusher, a holder and some care with a tight pin.

Correction note: an earlier version of this page said Khaki Field and Jazzmaster bracelets use screwed links. We found no evidence for that and several sources showing pins, so the page has been corrected.

Hamilton notes that resizing may be done at an authorized retailer. Hamilton's Khaki Field metal bracelet is sold with a quick-release attachment, so on those models a strap swap needs no tool.

  1. Find the arrows. Clean the inside of the links near the clasp and look closely, a loupe helps.
  2. Seat the link in a holder. Arrow down, both sides of the link supported.
  3. Push with the arrow. A bracelet press or a pusher that fills the pin hole. Straight, steady pressure.
  4. Keep the collar. It sits in the middle link and falls out once the pin clears it.
  5. Remove links evenly. From both sides of the clasp.
  6. Refit against the arrow. Collar in first, then the pin until it sits flush.

No arrow visible?

Hamilton arrows can be small and faint. Clean the inside of the links and look with a loupe near the clasp. If you still cannot find one, do not guess by force. Try gentle, even pressure from one side in a proper holder. If the pin does not move, try the other side with the same gentle pressure. A pin that moves easily in one direction is going the right way. A pin that needs a hammer blow is not.

The tight pinHamilton pins are often tight. Force must go straight through the pin with the link fully supported. A punch that slips lands on the brushed outer surface, which is exactly the surface you look at every day.

FAQ

Does the Hamilton Khaki bracelet have screws?

The Khaki bracelets we checked, Aviation and Pilot, use push pins, and the Jazzmaster uses pin and collar. We found no source showing screws on the Khaki Field either. Check your links for arrows before you start.

How do I remove links from a Hamilton watch?

Push the pin out in the arrow direction with a pusher and a holder, keep the collar from the middle link, remove links evenly on both sides of the clasp, then refit the pin against the arrow.

My Hamilton bracelet has no arrows. What now?

Look again with a loupe, they are often faint. If there really are none, test gently from each side in a holder. Never hammer blindly.
