pity that the hands are still wrong length size
yup seems like all factories are still using 116660 hands on 126660...Presumably like many of the "lesser" factories (and Rolex for the 116660!) they're just using hands from something else.
Gen 116660 pic from Chrono24 and my cheapie.
So, it's only a tell if you really know your stuff, I'll wager you'll find people saying gen 116660's are reps 'cause of the hand length!
