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!

BIWI 20mm Caoutchouc Rubber Strap

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.

Amazing Quality!

I typically don't like rubber straps but this strap is perfect! It it so comfortable on my wrist yet it still feels like my skin can breathe. I had originally purchased the Bronze Trekker with the blue dial and leather band and changed my mind to rubber after wearing. I was able to transfer the bronze buckle to the rubber strap and install this back on my Trekker! Now when I ski, the watch doesn't shift on my wrist and I'm able to see how much longer the lifts are open to get back to my car at the top lodge. :)
