How do you adjust a Seiko watch strap?

In order to adjust a Seiko metal watch strap, adjust the spring bar pin to the appropriate pin hole in the clasp by pushing in the end of the spring bar until it releases and sliding it into the next hole until it clicks, repeating on both sides of the bracelet link. A spring bar tool, thin screwdriver or a fine pin punch is most effective when adjusting the pin.

When adjusting a Seiko metal watch strap, take care in removing the pins and using the tools to avoid scratching the band. Links that are removable usually have an arrow on the underside.
