Expertly crafted in Italy for more than forty years, vanilla-scented Bonetto Cinturini rubber dive watch straps have long been trusted by renowned watchmakers for their perfect combination of durability and comfort. Made from high-quality vulcanized nitrile butadiene (NBR) rubber, these waterproof, nontoxic and nonallergenic straps are engineered to withstand seawater and UV radiation from sunlight. In addition, thanks to the repellent properties of NBR rubber (unlike silicone), you can say goodbye to lint and dust! With hundreds (and hundreds) of positive reviews, Bonetto Cinturini straps are a great choice for any watch enthusiast.
Model 328 is a sleek NATO style comprised of two thin, flexible layers with a finely ribbed texture and sandblasted stainless steel hardware. Prefer a single-pass configuration? Simply remove the "extra" strap piece and keepers, and you're all set.

It fit so good on my arm with my seiko!I love it!!!
This thin, light weight, flexible band with a nice amount of stretch is my go to pick for multiple watches.
I removed the extra pass of rubber and the extra metal keepers to create the most comfortable single pass strap I own.
This strap is very long apparently to allow wearing over a wet suit, but it cuts down very easily with a razor blade, knife , or sharp scissors to allow a custom length of tail after the keeper.
A plastic water bottle lid or coin made a nice guide for cutting the end to perfect length.
Ordering more for sure!
This was a great purchase. Was looking for an alternative to my factory Tudor rubber FXD rubber band. This easily converted to a single pass band by removing two spring pins and the secondary strap. Not as thick as the factory strap but cleaner and smoother. Good value.
