About The Rubber

Coming from Bonetto’s factory in northern Italy, this strap delivers strength, suppleness, comfort and simplicity. Its special rubber formulation is waterproof, saltwater and UVA-resistant for years of on-wrist pleasure. Not to mention it's non-toxic and non-allergenic. It’s also reversible, in case you want a change of texture.

Please note that the rubber will need to be cut in order to size the strap and that the width is tapered meaning that the buckle is 2mm narrower than the lug width. We recommend cutting a section at a time so as not to cut too much off the strap. We do sell spare rubber parts if a mistake is made.
