This strap smells like heaven.😎

One for regular usage

It is very elegant strap, can be used with both sports and dressed watch. It has thin profile with a solid feel and does not attract lint/dust. The underneath dotted pattern keeps the airflow and less sweaty. Most comfortable strap I have ever used. Mild vanilla scent is an added bonus. I have 6-3/4 inch (6.75") wrist and it fits perfectly to the second last hole from the clasp with 42mm watch.
Add-on black clasp is worth spending few extra bucks. It has brushed/matte look, strong feel and matches perfectly with the strap.
Excellent customer service, they know their stuff pretty well.

Not your typical cheap rubber

I dove (pun intended) into researching the best rubber straps I can pair with my dive watches. You’ll often see FKM rubber or silicone straps from other brands. Don’t bother with those. Bonetto Cinturini uses vulcanized rubber that has the one-of-a-kind sweet smell. Love that it doesn’t attract lint like the other cheaper options!


Great strap. Fast shipping and exactly as described.


Fantastic strap and service. This one is certainly a keeper. Thanks again!
