Strap recommendations by Louis Erard family
Excellence
Excellence models in this guide use 20mm straps. Covered examples include Excellence Petite Seconde 39 Aventurine. Choose the exact width first, then pick the material based on how you wear the watch.
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.
