Hi guys. This isn't a who has the best sub post, but I need some advice on gen sub c's
a good friend of mine is shopping around for a 116610 and has asked me for advice since he knows I'm into watches. Only problem is that my gen sub c knowledge is lacking
my questions are:
besides condition, is there a difference in a newer production/serial vs older?
are there any known issues with certain production dates or versions?
any red flags he should be looking for?
thanks again
Tony
