You can buy only half links? I saw just bundle watch + gift half linkThat's a V1. But don't worry, the dial difference is so small that you can hardly see it. I received my V1 yesterday and can barely read the IWC logo when the watch is on my arm.
As already reported by many, the bracelet fits very tightly on a 17.5 cm wrist. I have now ordered a half-link from Ixdao (Aliexpress)... I have a good feeling that it will fit.
