  • Align the remaining links and insert the pins back into place.
  • Ensure the pins are secure by pushing them in fully.

Adjusting the Clasp

  1. Locate the Adjustment Holes: Most folding clasps have multiple adjustment holes on the clasp itself.
  2. Move the Spring Bar: Use a spring bar tool to push the spring bar out of its current hole and move it to a new hole for a tighter or looser fit.

FAQs

How can I tell if my watch clasp needs adjustment?

If your watch feels too tight or too loose, or if it slides around on your wrist, it likely needs adjustment. A properly adjusted clasp should feel secure but comfortable.

Can I adjust my watch clasp at home?

Yes, many watch clasps can be adjusted at home with basic tools. However, for complex adjustments or high-end watches, you might prefer to visit a professional jeweler or watch repair shop.
