Fit notes before you buy

• Grand Seiko case finishing and bracelet end links are precise. Standard straps should match the lug width, but fitted end links and bracelets must be made for the exact reference.
• Use thinner, high-quality leather on dress and Heritage references so the strap does not crowd the case.

How to choose the right replacement strap

1. Confirm the lug width in millimeters. The strap width must match the inside distance between the lugs.
2. Check whether your watch uses standard spring bars, screw bars, wire lugs, curved end links, or a proprietary attachment.
3. 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.
4. If your watch has an integrated or shaped bracelet system, use a strap made for that exact reference instead of relying on width alone.
