How accurate is your Rolex?

Probably needs a COA - clean, oil and adjust. I have three different sizes and I notice that every two to three years one will begin to lose a few mintures here and there and that signals it's time for servicing.
 
All recent Rolexes (in the last decade or so) are COSC Certified. Meaning that they must be kept within a certain accuracy threshold. The acceptable loss/gain to attain the COSC is -+ 6 seconds.

If your Rolex came with a COSC certificate, and is losing/gaining more than 6 seconds, send it to your Authorized Dealer and have it serviced.

This is accurate. My father works with clocks and watches so I'm sure of it. If your watch is gaining or losing any more it needs to be serviced.
 
this is good info. both of my parents complain constantly about their watches not keeping time. my father even sent his to be serviced, and it still doesn't keep accurate time.
 
Looks like you are wearing the watch enough hours to keep it running continuously. The time keeping should therefore be within 6 seconds per day. If it is more than that I would have it checked by your Official Rolex Jewelers or an Official Rolex service center.

I have an old Rolex from the 1940's. It's a wind up, not automatic, which always makes the untrained suspicious. It's chronically (or should I say chronologically) challenged. It is about 15 minutes slow each week. I have sent it out to Rolex, the last time they sent it to someone in Switzerland and it still is slow. I just accept the fact that it's a bit off, like me!
