Gather a small pin pusher, spring bar tool, or paperclip, a hammer, and a soft cloth
Lay the watch band flat on the cloth
Locate the removable links and the arrows or pins on the inside of the band
Identify which links need to be removed from each side of the clasp to keep the watch centered
Position the band so the arrows point downward
Push the pin out in the direction of the arrows
Use the tool and gently tap the pin until it slides out
Remove the pin completely
Take out the desired number of links
Align the remaining links
Reinsert the pin in the opposite direction of the arrows
Tap the pin back in until it is flush
Repeat on the other side if needed
Check the fit on your wrist
Adjust again if necessary
