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.

Thickness
The watch strap thickness refers to the measurement of the strap's height or thickness. It is the distance between the top surface (the side facing away from your wrist) and the bottom surface (the side in contact with your wrist) of the strap. The thickness of a watch strap is an important factor to consider as it can affect the overall comfort, aesthetics, and compatibility of the watch with your wrist. | 4mm |

Strap
Width
Taper
A watch strap taper refers to the gradual reduction in width from the lug end to the buckle end of the strap, not all watch straps have a taper. For example, if a watch strap has a lug width of 20mm and a taper of 2mm, it means that the strap's width gradually reduces by 2mm at the buckle end, resulting in a final width of 18mm at the buckle, so would be refered to as 20mm/18mm. | 20mm/18mm, 22mm/20mm |
