Rubber straps are among the top-selling categories in the industry. They are cost-effective, fashionable and easy to wear. The one big issue is that they always come in a fixed size. We decided to change that.

Introducing the OPTO WATCH CO. Customizable Size FKM Strap 2.0. This new generation ensures you wear a perfectly sized strap on your wrist. It also follows the current trend with a tapered style.

In terms of design, the strap has a smooth, clean finish that suits larger watches. Its design language is non-intrusive. There are no loud patterns or heavy textures, just clean surfaces and a gentle taper from lug to clasp. The taper slims the strap down toward the wrist, so it looks refined and sits comfortably, and the finish lets your watch stay the focus.
