Metal watch bands are common on Swiss, Japanese and Chinese watches. There are many methods of adjustment. While some watches do not require special instructions or tools, the most common bands are pin- or screw-based. Pin-based bands require a driving tool to work with, and screw-based bands require either one or two screwdrivers.

Examine the watch links closest to the buckle. These links will contain holes to aid in removing the links. If the holes contain pins, continue to step 2. If the holes contain small screw tops, move to the screw-based band section.

Set the watch face down on a soft cloth. This will protect the watch from being scratched.

Locate the arrow underneath the band. These indicate the direction that you must push out the pins.

Push the link out of the band using the small driving tool. Pull the pin from the other side when possible.

Repeat step 4 to remove as many links as you need. If you remove more than one, remove links from both sides of the buckle for balance.

Rejoin the band by using a pin to join the remaining links and the buckle.

Set the watch face down on a soft cloth. This will protect the watch from being scratched.

Locate the screw heads on the links closest to the buckle.

Unscrew the link using the small screwdriver. Hold the opposite side with a second screwdriver if the link will not unscrew.

Repeat step 3 to remove all needed links. Remove links from both sides of the buckle for balance.

Rejoin the band using a screw to join the remaining links and the buckle.
