Model 298 is a one-piece, single-pass rubber watch strap built around a simple, traditional layout. The strap threads behind the watch and secures with a buckle and floating keepers, with the excess length folded back and tucked in. The design stays clean and functional, with an untapered profile and no extra shaping.

Material & feel

Made from vulcanized NBR rubber, the strap has a firm but flexible feel. It bends easily and holds its shape through regular wear, with a matte surface that keeps the look straightforward. The single-pass construction adds a layer beneath the case, giving it a slightly more substantial presence than a two-piece strap.

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

Fit guidance

Bonetto Cinturini one-piece rubber straps use a fixed-length design with a pass-through construction that accommodates a wide range of wrist sizes. Excess strap length is folded back and secured rather than trimmed, allowing the fit to be adjusted without precise length selection. The flexible rubber construction conforms more easily than stiffer one-piece strap materials.
