I had a WTB out for Sinn rubber for the U1 and then discovered them for sale at Chronomaster. Prior to that, and as a backup, I went looking for an interim solution.
I came across Elliot Brown and thought I would give one a whirl, if it didn't fit the U1 I am sure it would find its way onto something else.
Anyway, it arrived today and fits like it was made for the watch. Nice and thick at the lug end, slim at the buckle, good quality and the black hardware looks great! What do you think?
