CTS FKM Curved-End Rubber Watch Strap 21mm 22mm 24mm – Butterfly Clasp
About this item
Upgrade your compatible watch with this CTS FKM curved-end rubber strap, designed to combine a fitted case connection with a customizable wrist fit. Made from durable FKM fluororubber, the strap offers a flexible feel, strong resistance to everyday moisture and wear, and a clean sport-watch appearance.
The molded curved-end profile is intended for selected watch cases with matching lug geometry, while the cut-to-size construction allows the strap length to be trimmed progressively for a more tailored fit. A stainless steel butterfly folding clasp provides a secure and balanced closure for daily wear.

The CTS construction allows excess strap length to be removed gradually from the clasp end for a more customized wrist fit.
- Measure your required length before trimming
- Remove only one adjustment section at a time
- Check the fit after each cut before removing more material
- Keep both strap sides balanced for proper clasp positioning
Important: Cut strap sections cannot be restored. Once the strap has been trimmed or permanently modified, it may no longer qualify for a change-of-mind return. Please confirm sizing before cutting.
