What time is it? Watches and horology

"This one is in almost unmarked condition" is the usual watch dealer bullshit.

It's been polished, obviously, but not a crazy amount. It looks a bit softer around the crown guards than I'd like but overall it's not the worst.

Dial has almost certainly been replaced (it's a luminova dial, which is correct, but I think it's from a slightly later style of the 16710 - might be a service dial fitted by Rolex, there should be receipts confirming this if so). Very probably the hands and the bezel insert too (would be interesting to see if the papers confirm it was a BLRO - ie Pepsi - originally or not). But most of them are like that now (because conscientious owners have their watches serviced) and in this case I think the price reflects it. I wonder if the bezel insert has been fitted slightly askew. That can be fixed though. It's on the correct bracelet.

Would be interested to know service history, and if there are receipts for that. How is it running? How recently has it been serviced? No mention of that on the listing which is a bit of a red flag.

Overall, it's a nice looking watch and the price isn't ridiculous. But if it hasn't been serviced recently, or by Rolex, you probably need to factor a service in.

All good advice. ^ Also check if the IMS has been changed for the dual bearing one and get a rev range report.

Looks like a little mark to the case around the 11 marker.
Dial looks wonky?
around the crown looks pretty polished quite a bit imo - could just be the lighting but above the bracelet looks q different to below.
Basically need to see in person
