Bonetto Cinturini 315 Rubber Watch Strap - Black
Made in Italy from vulcanized NBR rubber. Waterproof, UV-resistant, and nonallergenic.
Rather than relying on waves or cutouts, Model 315 uses shallow beveled embossing to give the strap definition. The angled detailing runs along the top surface and catches light just enough to add depth, while the overall profile stays slim and controlled. Visually, it reads quieter and more refined than most traditional dive straps. This design is about restraint. The slimmer build and softened geometry make it a good match for modern sports watches and everyday tool watches where rubber is appropriate, but heavy dive styling would feel out of place. Double keepers add stability without disrupting the clean lines.
Material & feel
Vulcanized nitrile butadiene rubber (NBR) is used for its durability, flexibility, and resistance to seawater and sunlight. The vulcanization process gives the strap structure while preserving an easy, natural bend, so it wears comfortably without feeling soft or floppy.
On the wrist, Model 315 feels light and composed. The beveled embossing adds surface interest without stiffness, and the textured underside helps reduce surface contact, improving airflow during extended wear. Compared to more sculpted Bonetto models, this one feels smoother and more understated.
Carries a light vanilla scent, typical of Italian-made vulcanized rubber.
