Bonetto Cinturini is an Italian family-owned manufacturer of watch straps founded by Ottorino Bonetto near Vicenza, in the Veneto region, where it has been producing vulcanized NBR rubber straps for over 40 years. For two generations, the company has specialized exclusively in one precisely defined product: premium-grade rubber straps supplied under its own brand to watch collectors and dive watch enthusiasts, and in parallel as OEM straps to the watchmaking workshops of the world's largest luxury brands.
Family Tradition and Decades of Specialization
Bonetto Cinturini was established as a rubber goods manufacturer focused solely on watch straps. Founder Ottorino Bonetto developed proprietary NBR rubber compound formulas that have evolved over decades while never losing their defining characteristics: exceptional wearing comfort, aging-resistant flexibility, and resistance to water, sweat, and chemicals. Today the company is run by his daughter Matilde, and every strap leaving the workshop in Rettorgole di Caldogno undergoes hand finishing and quality control. Bonetto Cinturini serves as an OEM supplier to some of the most respected watch brands in the world.
NBR Technology and Material Properties
The NBR (nitrile-butadiene rubber) used by Bonetto Cinturini is a proprietary compound developed in the company's own laboratories. NBR is defined by outstanding resistance to oils, gasoline, ketones, and other chemicals, excellent flexibility across temperatures ranging from -40 to +100 degrees Celsius, no hardening or cracking with age unlike standard rubber, and hypoallergenic properties confirmed by REACH and RoHS certifications. The material composition has undergone independent laboratory testing confirming non-toxicity and minimal reactivity with human skin — particularly important for users wearing a watch around the clock, during athletic activity, and in demanding environmental conditions.
Models and Design
The Bonetto Cinturini catalog covers several dozen numbered models: classic vintage-style designs (the model 295 with its distinctive ribbed pattern), more recent sport designs with perforated patterns, and models precisely matched to specific dive and sport watches. The color range is extensive — from classic black through browns and navy to bold red and yellow accents popular on sport timepieces. Available widths from 16 to 26 mm make it possible to fit virtually any watch that calls for a premium rubber strap.
Military and Sport Applications
Bonetto Cinturini straps are particularly well regarded among military and dive watch users: G-Shock, Seiko Prospex, Citizen Promaster, Casio Rangeman, and other watches with standard spring bars that require a strap resistant to water and sweat. Tactical watch and pilot watch enthusiasts appreciate the durability and comfort of NBR rubber during extended wear in uniform, at the range, or in the field. Compared to leather straps, NBR rubber does not absorb water, sweat, or mud and maintains full functionality under the most demanding conditions.
