Identify the type of strap: resin, metal, leather, or fabric
For resin or rubber straps, remove the watch from your wrist
Locate the buckle and choose a tighter or looser hole
Insert the pin into the desired hole
For metal bracelets, find the removable links
Use a spring bar tool or small pin tool to remove the link pins
Remove the needed number of links
Reinsert the pins securely
For leather straps, move the buckle tongue to a different hole
For straps with a clasp, open the clasp and adjust the micro-adjustment holes if available
Make small adjustments and test the fit
Ensure the watch sits snugly but not too tightly
Verify that the buckle or clasp is fully secured before wearing
