Model 284 is one of the most substantial dive straps in the Bonetto Cinturini lineup. The thick wave-patterned profile, perforated body, and reinforced keepers reflect the oversized rubber straps historically associated with professional Seiko dive watches, including Bonetto’s Tsunami motif at the tip. Its longer length and heavier construction suit large modern dive cases that can feel undersized on slimmer rubber straps.

Material & feel

Model 284 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 without feeling soft or unstable.

Compared to slimmer Bonetto models, this strap feels noticeably more substantial. The thicker profile adds structure and weight, helping it balance larger cases while remaining comfortable during extended wear. The matte surface resists lint and dust more effectively than many silicone straps and maintains a clean, utilitarian appearance.

Carries a light vanilla scent, typical of Italian-made vulcanized rubber.
