Bonetto Cinturini is an Italian manufacturer with more than forty years of experience producing rubber watch straps for professional and everyday use. The brand specializes in straps made from vulcanized nitrile butadiene rubber, selected for its durability, flexibility, and resistance to seawater and UV exposure. Bonetto Cinturini straps are widely used by watch manufacturers and enthusiasts who value long-term performance, comfort, and straightforward, functional design.
Model 285 is defined by its bold wave profile. The sculpted sections are larger and more pronounced than on other Bonetto Cinturini wave straps, giving it a strong, graphic presence that reads unmistakably “dive watch” on the wrist. Round perforations run the length of the strap, adding ventilation without breaking up the overall silhouette. This model favors visual impact over restraint. It’s a good choice when you want a classic dive-strap look with real presence.
Model 285 is made from vulcanized nitrile butadiene rubber (NBR), selected for its durability, flexibility, and resistance to seawater and sunlight. The vulcanization process strengthens the material while maintaining controlled flexibility, allowing the strap to bend naturally without feeling soft or unstable.
Compared to slimmer Bonetto models, Model 285 has a firmer, more structured feel that supports its larger wave design. On the wrist, it feels stable and secure, with enough give to remain comfortable during extended wear. The matte surface resists lint and dust more effectively than many silicone straps and keeps the overall look clean and utilitarian.
Carries a light vanilla scent, typical of Italian-made vulcanized rubber.
Model 285 is a longer, thicker rubber strap intended for larger wrists and heavier watches. It may wear long on smaller wrists. A double floating keeper helps manage excess length. Accommodates spring bars up to 2.5mm in diameter.
