Do I need to be concerned about removing the case-back on a used model. I have a friend selling a 16610. I removed the case-back to take a look at the movement. He said he was ok with it but then when I was finished he started to freak a little bit. He thought since it was due for service soon (purchased in 2004 so it might be over due) that my removing the case-back may have compromised the depth rating.

Anyway I decided not to buy it and now he wants me to subsidize part of the service. Of course I told him to go pound sand, in a nice way. Given that he agreed to let me look at the movement and that any service needed is his responsibility, I don't feel guilty. I still wondered if he had a point about it possibly being compromised in someway though.

thoughts?

Marc, any time a case is opened it's possible that the waterproofness has been compromised. The seal may not be re-seated corrrectly when closed. Not sure what this would cost on it's own as I have not done this without having paid for a complete service.

Marc, I'm assuming you didn't use grease on the gasket when closing or fomblin on the threads? There's a slight chance that water tightness may have been compromised. Only a test would prove it. It's probably fine and if your friend is sending it in for service then it's moot. I generally will only open watches after I've purchased a watch and obtained a return policy if something is wrong - it avoids these situations.

All things aside this says it all IMO.

So he can't dive to 300m until next service.

Most any high street watchmaker could pressure check and when case back is removed for any reason its always wise to pressure check after if used in water.But myself have done it several times and never had any problems with any water after pressure check.

Thank you gentlemen! I appreciate the information!

The chances of anything going awry after simply openning the watch then closing it are slim to remote especially on a 16610. Unless he has no access to Rolex parts gaskets are inexpensive and sealing it up is basic watchmaking 101. I would never tell a prospective buyer that I would charge them to open and inspect that's ridiculous. IMO. Rikki
