The WatchGecko TidalPass was inspired by classic British Military watchstraps, but with a WatchGecko twist. Instead of the traditional nylon, we have made it out of FKM rubber, a premium rubber which is known for its particular resistance to wear and extreme temperatures. And we have given it two floating keepers, so you can wear it with the traditional streamlined look, or else double it back like a classic military strap, for enhanced security on your wrist. Being rubber, it is of course waterproof, ideal for diving watches, but its low profile (just 1.5mm thick) suits it for a wide range of watches, including tool watches and vintage diving timepieces. Coming complete with a rugged stainless steel pin buckle (acid-etched with the famous WatchGecko logo, so you know it's authentic), this strap is the perfect three-way marriage of timeless style, durability and comfort. With a total length of 245mm, it fits wrists between 165mm and 220mm. The strap holes are spaced 5mm apart, to ensure the perfect fit.
