Hi Simon, hi everyone
I have the exact same problem on a wonderful PAM164 I got from a respected member here in RWG. I am quite certain that I messed the movement up while trying to set the date at the wrong time. Stupid me.
I have read Pug's excellent tutorial for a date wheel swap and contemplate trying to fix the problem myself (I'm in Switzerland, sending watches around is dangerous and finding a local Rep friendly watchmaker nearly impossible).
I'm not too savvy working in movements. Experts, I'd be grateful for the brutal truth: Do I stand a chance fixing this myself or must I look for another way?
Sorry Simon, not meant to highjack your thread, maybe this could be interesting for you too.
Kind regards
Valerian
