How to choose the right replacement strap
- Confirm the lug width in millimeters. The strap width must match the inside distance between the lugs.
- Check whether your watch uses standard spring bars, screw bars, wire lugs, curved end links, or a proprietary attachment.
- Match the material to the case: leather for dress wear, rubber or FKM for water and sport, NATO or textile for casual tool-watch wear, and steel only when the end-link fit is correct.
- If your watch has an integrated or shaped bracelet system, use a strap made for that exact reference instead of relying on width alone.
