Expertly crafted in Italy for more than forty years, vanilla-scented Bonetto Cinturini rubber dive watch straps have long been trusted by renowned watchmakers for their perfect combination of durability and comfort. Made from high-quality vulcanized nitrile butadiene (NBR) rubber, these waterproof, nontoxic and nonallergenic straps are engineered to withstand seawater and UV radiation from sunlight. In addition, thanks to the repellent properties of NBR rubber (unlike silicone), you can say goodbye to lint and dust! With hundreds (and hundreds) of positive reviews, Bonetto Cinturini straps are a great choice for any watch enthusiast.

Model 284 is ideal for your Seiko Tuna. The tip features a Tsunami wave symbol, and the strap is perforated for improved air circulation. To ensure that the band stays securely in place, a double perforated floating rubber keeper is included.
