Originating from Vicenza, Italy, Bonetto Cinturini creates OEM rubber dive straps for multiple renowned watch brands. This family-owned company has been in business for more than forty years. Bonetto Cinturini straps are made of high-quality vulcanized nitrile (NBR) rubber, providing waterproof, non-toxic, and non-allergenic properties. They do not collect lint and dust like silicone rubber and are resistant to salt and UVA rays. In addition, they have a subtle, pleasant vanilla scent.

Model RX01, shown here in Nero/Black, is expertly designed specifically for Rolex, with curved ends for a seamless fit between strap and watch case. The reinforced lug ends ensure that no splitting or cracking will occur around the spring bar.
