At the moment I have three watches on Rubber B. Perfect fit around the case face and back and on the lugs. These 3 straps also fit the Sub 16610, GMT 16710 and SeaDweller 16600 all 40mm (not that I own all of those
). The strap fitted to the Rolex clasp tapers down from 20mm down to 15mm, the other two taper down from 20mm down to 18mm. The difference in taper is obvious on the group photo. Made of a soft, flexible rubber and wears very comfortable on the wrist.
