I would proceed with extreme caution. I tried replacing a lightly scratched bezel on a Citizen Orca titanium dive watch with a brand new one that I bought directly from Citizen. I couldn't get the old one off so, as a last resort, I dropped both the watch and the new bezel off at a local watch repair place. I explained to them how rare the watch was and that it was made from titanium. The owner of the shop said that they'd have no problem with it.
They couldn't get it off after about a week of trying. The owner called me and asked if it would be OK to send it to Citizen's repair center in Southern CA. I said OK.
About a week later I got my Orca back and it was scratched, gouged, and dented beyond belief. I was totally speechless. Oh, and to make matters worse, the "new" bezel that was on my Orca was scratched too! :headbang:
Lessons learned:
1. I *ONLY* work on my own watches - no exceptions! Nobody, and I mean ABSOLUTELY NOBODY will care for my watches like I do, no matter what the "professionals" say to my face and in person.
2. Never use force to remove a dive bezel. If it doesn't come off with a little bit of gentle effort, just give up and live with it as-is.
