This page attempts to explain how to remove links in a metal link watch bracelet so that it will fit your wrist correctly.
The bracelet in the example is from a Seiko diver's watch but is similar to the ones found on Citizen, Invicta, Orient, Casio, and many other watch brands.Click the pictures below for a larger view.
Images Comments Tools which can be used to push the pins out are: A - Bergeron 3153 pin and spring bar tool.
B - A diaper pin (of the correct diameter) with the point ground flat.
C - A plastic tipped mallet (for driving pins in without scratching the links).
D - A pin vise with a small number drill inserted backwards makes a great pusher.
E - A drill index containing number drills 61-80.Start by removing the spring bar from the clasp to separate the bracelet into 2 parts.
Use the pushpin tool to compress the spring loaded tip and tilt the bracelet end out.NOTE: the spring bar is spring loaded so make sure that it does not fly away when removing.
Look at the side of the bracelet and observe that several of the links have what appear to be small screws in holes in the side of the bracelet.
These are the removable links.NOTE: although the pins may appear to be small slot head screws they are not and attempts to turn them with a screwdriver may damage or distort them.
Removing the pin.
Insert the pin removal tool into the bracelet link and push squarly and firmly in the direction of the arrow stamped on the link.
The pin should start to move out the opposite side, at first the pin has a good amount of resistance, once the enlarged head has cleared the shoulder in the link it will move much easier.NOTE: sometimes a large amount of force is required to get the pin started.
If the force is too much or the pin pusher starts to bend, stop and check to make sure that the bracelet really has pushed pins and not screws (screws are mostly found on high end Swiss watches, I have not encountered an Asian made bracelet with screws yet).The link is shown separated from the mating links. It is helpful to keep the pins and links oriented the same way that they came apart to facilitate reassembly.
Pushing the pin back in to rejoin the links.Push the pin back in from the opposite side that you pushed it out. A flat drift larger than the pin should be used to push the pin flush with the side of the link. NOTE: after the pin is flush with the link take the pin removal tool and push it a bit further in (you may hear a faint click as the enlarged head of the pin snaps back into the shoulder inside the link).
When correctly inserted there will be no protrusion of the pin on either side of the link.
Make sure to save all leftover pins and links as thay may be needed if the watch is sold to a person with a different size wrist.
