Metal watch bands are not "one size fits all." Pulsar has designed its watch bands to be easily adjusted, especially if you need to make them smaller.
Wrap the watch band around your wrist to determine how many links need to be removed for the watch to fit properly.
Place the watch face-down on a flat surface.
Look on the back of the watch band. You will find an arrow that indicates which direction you should push the pins to remove the links.
Find the point at which the extra links need to be removed for your watch to fit your wrist. Using a 1 mm flathead screwdriver (or the edge of one side of a pair of tweezers), push the pins in the direction indicated by the arrows.
Finish removing the pins with your pliers.
Keep the extra links in case you ever need extra room on your watch band.
