This is my thinking, it's legal, but I'm concerned that if they might still take a dim view of it not being a branded gen watch, I'm wondering if that would attract the same attention/consequences as a rep... I've visited France a couple of times on coach trips, so never really gone through customs as anything more than a guy making sure everyone on the coach had their passports. Never had any issues with customs in Spain, and equally, no issue wearing a GMT through Japanese customs either, despite there being a wall of counterfeit goods right by the customs department, and the fact that I 'drew attention to myself' when leaving, as I forgot to remove my belt and its camera case when going though the scanner (with said GMT sitting in the tray with my phone ) I think I just got lucky on that occasion I'm wondering if maybe the 'issue' was because Donerix was wearing a PAM, which is a pretty noticeable watch, where a DateJust or Seamaster might have slipped under the radar...
