The WatchGecko 400 Italian rubber diver strap with bushed/polished deployant clasp is a high-performance, bracelet-style strap designed for serious use-whether you're exploring the deep or facing the elements outdoors. Now paired with the WatchGecko Divers Deployant Buckle, this strap-and-buckle combo delivers enhanced comfort, refined style, and total reliability.
Crafted in full collaboration with renowned Italian rubber specialists Bonetto Cinturini, the 400 model features a unique embossed carbon fibre design and benefits from over 30 years of strap-making expertise. Resistant to saltwater, UV, and harsh environments, it’s an ideal choice for dive and survival watches—especially striking in orange.
Now equipped with our engineered deployant clasp, you’ll enjoy seamless adjustability and all-day comfort. Designed for intuitive use and built from 14 precision-machined components, this buckle complements the strap’s rugged reliability with a refined, modern finish.
Also available in two additional buckle finishes: IP Black and Super Luminova

About The Rubber
Coming from Bonetto’s factory in northern Italy, this strap delivers strength, suppleness, comfort and simplicity. Its special rubber formulation is waterproof, saltwater and UVA-resistant for years of on-wrist pleasure. Not to mention it's non-toxic and non-allergenic. It’s also reversible, in case you want a change of texture.
Please note that the rubber will need to be cut in order to size the strap and that the width is tapered meaning that the buckle is 2mm narrower than the lug width. We recommend cutting a section at a time so as not to cut too much off the strap. We do sell spare rubber parts if a mistake is made.

Size Guide
