Vintage Rolex is easier to spot LOL! It's the new ceramic models that are popular, and cloned close to perfection. Look at the example few pages back!
I only need one pic to know Sleepyman's 1680 is a fakey! pui! Honestly, I gave more than 2 easy pointers to spot it's a fake. Even if he defends it's a fraken, patui! Ok, maybe, everything is fake except for the movement inside LOL
only stupid vintage owners bring their watches back to Rolex and AGREE to replacement of parts. These are mostly the younger kids who inherited their father's rusty old datejusts. Sigh. I've seen a few idiots who did just that.
if you're one of those kids... please please please know that the rustier it is, the more orange the patina is, the more 'furry' the dial is... it's more beautiful! The only part which you're kinda allowed to replace is the hairspring!
