Introducing the WatchGecko Radius Cut to Size (CTS) Rubber Watch Strap, designed with a bold modern look and engineered for all-day adjustability, this strap combines dependable performance with an expressive edge - ideal for those who want their watch to stand out as much as it fits in. Its CTS construction allows for a truly tailored fit: simply trim the strap using the eight notches on each side, spaced at 4mm intervals, to match your wrist perfectly.
Paired with a spring-loaded leaf buckle that offers fine-tuned micro-adjustment, delivering one of the most adaptable and wrist-friendly fits in our rubber watch straps line-up. Crafted from stainless steel, the buckle features a combination of brushed and polished finishes for a refined look. It’s left unbranded to maintain the strap’s clean, modern aesthetic and keep the focus on your watch.
Its design is defined by two raised, parallel lines running the full length of the strap, adding both texture and a sense of streamlined movement. These subtle ridges not only enhance the strap’s visual appeal but also reinforce its dynamic, athletic character. Along with the integrated quick-release spring bars make installation tool-free and effortless, while the spring-loaded leaf buckle offers micro-adjustability for on-the-go fine-tuning.
If you need to remove the quick-release spring bars, then you can learn how to easily remove quick-release spring bars in our video.

Sizing The Navy CTS
Getting the perfect fit is easy with the Radius' Cut-to-Size (CTS) system. Start by removing the spring-loaded buckle using a spring bar tool. On the underside of each strap section, you’ll find eight clearly marked notches, each spaced 4mm apart. Trim one notch at a time, checking the fit as you go to avoid over-cutting.
Once trimmed, reattach the buckle and use the built-in micro-adjustment mechanism to fine-tune the final fit. This combination of CTS trimming and micro-adjustability ensures a secure, custom fit with a clean, professional finish - no excess, no bulk, just comfort.
