Many Seiko bracelets use a pin and a tiny collar to hold each link. They are easy to resize once you know the trick, and easy to ruin if you lose the collar. Here is how to do it.
What you need
- A pin pusher or link removal tool
- Tweezers
- A small tray or a white cloth so nothing rolls away
Step by step
- Find the arrows on the inside of the links. They show which way the pin comes out.
- Line the tool up with the pin hole, with the arrow pointing away from the tool’s handle, and turn or push slowly.
- As the pin comes out, watch for the collar. Catch it with tweezers and keep it with its pin.
- Remove the same number of links from each side of the clasp. If it is odd, take the extra one from the 6 o’clock side.
- To reassemble, put the collar back in its link, then push the pin in against the arrow until it sits flush.
Get the fit right
Seiko recommends leaving a little clearance, about a finger’s width, so air can circulate. A slightly loose bracelet is more comfortable than a tight one, especially in heat.
When to stop
If a pin is stuck, bent or sticking out, stop. Seiko says to stop wearing a watch with a protruding pin and have it repaired, because a loose pin can let the watch fall off.

Frequently asked questions
Which way do I push the pin out?
In the direction of the arrow printed on the inside of the link.
What is the tiny tube that fell out?
That is the collar. It holds the pin tight. Don’t lose it, as the link won’t stay together without it.
How tight should the bracelet be?
Seiko suggests leaving enough room to fit a finger between the band and your wrist.
