Great strap

I’ve been on the hunt for a new rubber strap for my Damasko. After a lot of searching, I stumbled onto this and gave it a try. Really a very nice feel. Soft but not too soft. Probably silly but I care that it isn’t made in china. I would prefer to have one of the keepers fixed, but besides that, I’m very satisfied.

Amazing Strap!

This unassuming strap is so very nice in person. This soft, flexible strap has quickly become my favorite strap for the Solitude. I cannot more highly recommend everyone to pick one up. They are work double the price!

Caoutchouc straps

Smooth and pliant. No dust or lint unlike silicone straps. Love it

Awesome strap!

Very soft and supple but still tough and secure. Highly recommend!

I love it! Soft and study. BIWI makes great rubber watch straps. I wish you guys could also stock the BIWI Osiris model in 20mm and 22mm.
