Had to make a trip to the AD today to drop off my gen Master II that took a crap today,main spring.It was way over due for a R&R..oh well just money.But I had my new rep Explorer on the one with the totally wrong crown but I was wearing it on my right arm so you couldn't really see it...salesman said OH I see you have a backup to use until you get your GMT back...Just said,"yep"!I tell you if this had a correct crown you couldn't tell it from a gen.
