Bansenshukai Posted November 21, 2006 Report Share Posted November 21, 2006 I acquired a vintage (1940 - 1950's) Omega. It is a hand wound watch. Well, I banged it too harshly against the side of my closet by accident and the minute hand fell off. Now, I have the tools to put it back in place, but I'm not sure how to remove the back. The back has no markings except a small inscription that says "18 KT" inside of a engraved box. So, I tried to turn it to remove it, but have gotten no effect. Do I pry it open? How do these things open? I don't want to try the wrong thing and break it. Thanks in advanced. Quote Link to comment Share on other sites More sharing options...
marrickvilleboy Posted November 22, 2006 Report Share Posted November 22, 2006 take a photo of it so i can see how the case was fitted. Quote Link to comment Share on other sites More sharing options...
ubiquitous Posted November 22, 2006 Report Share Posted November 22, 2006 Probably a snap back case. If you have a razor blade, you can wedge it between the case and the back; this will span a small gap which will allow for a larger blade to be inserted to pry the back off.

Sherrington Posted November 22, 2006 Report Share Posted November 22, 2006 If it's a snap back, which I would suspect it is, then DON'T use a sharp knife or a razor blade or you will certainly damage the case. What you need is a Bergeon (or similar) case back opening knife which is especially designed to do the job. They are not expensive, but being like a blunt knife will allow you to twist of the case back without damage to the case. Quote Link to comment Share on other sites More sharing options...
Pugwash Posted November 22, 2006 Report Share Posted November 22, 2006 What you need is a Bergeon (or similar) case back opening knife which is especially designed to do the job. Or, what we in the IT trade call a "Black Stick" which is a nylon stick used to pry laptop cases and iPods apart. @Nouns Defions, is your name a pun on something? It sounds like you wanted a military name like "Nous Defions" but ended up with a pun about being decidedly defiant with your fellow words.

Have used a razor to start a gap for a blunt edge with much success... Quote Link to comment Share on other sites More sharing options...
