Ok, change in topic: I got a leather strap from Bulang/Sons that I really like on this sub, but it rubs the case, which I’ve read is pretty common for these newer subs. The distance between the case and the lugholes is on the shorter side.
I don’t care about the strap, it’s distressed leather and won’t be damaged. What about the case? Should I worry that the serial numbers will rub away after a while? I sort of doubt it since there really isn’t that much motion between the case and the strap when I wear the watch.
