Made in Italy from vulcanized NBR rubber. Waterproof, UV-resistant, and nonallergenic.
Model 328 translates the classic military pass-through strap into rubber, with a broad one-piece layout, fine ribbed texture, and simple hardware. The flat profile and uninterrupted surface give it a straightforward utilitarian look that suits tool and dive watches especially well. The removable secondary layer allows the strap to be converted from a traditional double-pass layout to a lower-profile single-pass configuration.
Model 328 is made from vulcanized nitrile butadiene rubber (NBR), a material chosen for its durability, flexibility, and resistance to seawater and sunlight. The vulcanization process strengthens the rubber while preserving a controlled, supple feel.
The strap is constructed from two thin layers of rubber, each about 1.5mm thick, creating a structure that bends easily around the wrist. The finely ribbed texture provides subtle grip and visual definition while remaining understated compared to heavily patterned rubber straps. Sandblasted stainless steel hardware reinforces the utilitarian character and keeps reflections muted.

Bonetto Cinturini military G10 rubber straps use adjustable keepers to set the fit on the wrist. Excess strap length is folded back and secured rather than trimmed. The secondary pass-through layer can be removed to convert the strap to a single-pass configuration with less height under the watch.
