Thanks for pointing that out! You're right-Rolex serial numbers have been random since around 2010. It's best to check other details and get a professional verification for authenticity. 👍⌚
The Oyster Perpetual Cosmograph, like other Rolex watches, typically has a serial number engraved on the case between the lugs at the 12 or 6 o'clock position. If you're referring to a number behind the band, it could possibly be a reference or model number, but not the serial number.
another video says the serial number is always at the 6 ok clock side of watch, you say the serial number is at the 12 o clock side ? hhmmmm i wonder which side its on
Some have the serial number on one side and the model number on the other. Personnelly my model number is on the inside while the serial is on the 6 o'clock
