Hello, New guy here, I have a couple of questions, I bought a Omega sea master professional in 2001, I have worn it 24/7 and recently had to buy a new deployment clasp as the old one was worn out, I have over 100 ocean dives on this watch and it has started to loose time. can anyone tell me a good place to get it serviced and pressure tested. Also I recently I bought a Omega sea master PO from a high end dealer who is not an AD, the warranty card that did come with the watch does list an AD on it, would this watch be covered by factory warranty. Also how would I be able to tell if the watch is a 2500 c or a 2500 d. ser number is 85219xxx. thanks in advance. ron.
