How to resize a Seiko bracelet
Two link types, one common mistake, and about fifteen minutes.
By Stephen V. · Updated Jul 24, 2026
Seiko uses two link systems. Pin-and-collar links are pushed out with a pin pusher in the direction of the arrows on the bracelet’s underside, and each has a tiny collar that must not be lost. Screwed links unscrew with a small flat-blade driver. Remove links evenly from both sides of the clasp so the clasp stays centered.
Identify which system you have
Turn the bracelet over. If you can see small arrows stamped on the inside of the links, you have pin and collar — the arrows show the direction the pin must be pushed out. If you see slotted screw heads on the side of the links, you have screwed links.
Most Seiko factory bracelets in the entry and mid range use pin and collar. Aftermarket bracelets — the ones worth upgrading to — usually use screws, which is one of the reasons they are worth upgrading to.
Pin and collar, step by step
- Lay the bracelet on a soft cloth. This is not optional — a slipped tool lands on the bracelet, and a cloth is the difference between a near miss and a permanent scratch
- Find the arrows on the inside of the link and note which way they point. That is the direction the pin comes out; pushing the other way will not work and will damage the link
- Support the link in a bracelet holder or against a hard edge, and push the pin out with a pin pusher
- Catch the collar. A tiny brass or steel sleeve comes out with the pin and it is easy to lose in carpet. Work over a tray
- Reassemble by seating the collar in the link first, then pushing the pin back in against the arrow direction until flush
Screwed links
Simpler. Use a small flat-blade driver that fits the slot properly — one that is too small will chew the head. A drop of removable thread-locker on reassembly stops the screws backing out over time, which they otherwise do.
Which links to remove
Take them evenly from both sides of the clasp. If you remove three links, take two from one side and one from the other rather than three from one — otherwise the clasp ends up sitting off-center on the underside of your wrist, which is both uncomfortable and visible.
Keep the removed links. Put them in the watch box. You will want them if you sell the watch, and wrists change size.
Sizing it correctly
Aim for a bracelet that lets the watch move about a centimeter along your wrist but does not slide over the wrist bone. Size it in the afternoon — wrists are measurably larger later in the day, and a bracelet sized first thing in the morning is often uncomfortable by evening.
Most Seiko clasps also have a micro-adjustment: two or three positions where the spring bar holding the clasp can be moved. Use that for the fine adjustment after you have the link count roughly right.
When to let a shop do it
If the bracelet is expensive, if the pins are seized, or if you do not have a proper pin pusher. A jeweler will usually do it for a small fee, and one scratched link costs more than that.

Questions
What tool do I need to resize a Seiko bracelet?
A pin pusher for pin-and-collar bracelets, or a small flat-blade screwdriver for screwed links. Both come in basic watch tool kits costing a few dollars.
Which way do Seiko bracelet pins come out?
In the direction of the arrows stamped on the inside of the links. Pushing against the arrows will not work and can damage the link.
What is the collar on a Seiko bracelet pin?
A tiny sleeve that sits inside the link and grips the pin. It comes out with the pin, is very easy to lose, and the link will not hold without it. Work over a tray.
How many links should I remove?
Enough that the watch moves about a centimeter along your wrist without sliding over the wrist bone. Remove them evenly from both sides of the clasp so it stays centered underneath.
Should I resize a bracelet in the morning or evening?
Afternoon or evening. Wrists swell measurably through the day, and a bracelet sized first thing often feels tight by the end of it.
