Hello, I have a co-worker who is showing me (this week) some of his "supposedly" gen rolex watches and wants to sell me one, he claims he is in dire need of cash. So he's telling me he sells me his Rollie Sub aluminium 16610 (used of course) for a cheap price, $1000 USD, which is ridiculous because on chrono24 the cheapest 2nd hand 16610s go for $4000 USD. I don't knw why but he seems like a little deceptive, maybe the watches are stolen or something or are super reps, that doesn't make much senses because for the price he's selling you barely can buy a super rep like a franken TC Sub v6. I know the common tells between a super rep like a TC Sub V6 vs a Gen 16610,but what about a franken super rep, like a TC Sub V6 with franken bezel/insert and crystal/crown. Are there "common" tells to distinguish between a gen 16610? He claims he can't have the watch opened because he doesn't have the time to take it to an AD to have it identified as gen, but the will let me look at it even through a loupe. I know that its supposed to have a gen 3135 movement, so if I play the crown to set the date / time etc I will know if its an ETA or a 3135 (could be a yuki 3135 though!) by watching the hands movements CW/CCW in respect to the crown movements, but the concrete question, Are there any other less known tells, like the hand stack? I have read somewhere about this but can find the information and haven't been able to find anything despite a through and time consuming research on google and all the other forums. I don't want to expend cash on a super rep pretending to be a gen! I'd rather knw its a super rep and decide to buy it -or not- as I already have a TC Sub V6 with a gen insert. Thank you very for reading and I would appreciate your help! Best regards
