Omega Battery Replacement

[Syncopator]

Quotations from various jewellers and watch shops for changing the battery  have varied from well above average to the astonishing.    

 

There is nothing on the watch  and nothing in its accompanying manual which says it is waterproof. 

 

It is nearly 11 years old and previous battery changes were carried out by Omega.  

 

Being dexterous and having several watch back opening tools I have replaced batteries in many watches. 

 

Is there any good reason why I shouldn't change this battery myself?

Nothing what so ever as long as you take your time and be very careful. Surprising how jelly hands kick in when you start to work on a more top end watch!!...although most probably a plastic movement spacer in there!!..

If you do not consider the watch to be waterproof anyway and therefore take the necessary precautions to keep it out of the wet stuff, and you have appropriate tools then you have little to lose by opening it up and changing the battery yourself. If when you open it up you find it has a case back gasket then you might want to replace that as well (or at least apply a smear of silicon grease).

Don't be tempted to use a cheap battery though, invest in a decent quality silver oxide battery (avoid alkali batteries at all costs) as it will last longer and present less risk of leakage.

Thank you to both of you. 

 

Then I shall go ahead.

The gap for the opening blade, between the back and the case, is rather smaller than I have encountered on other watches and my two blades are not going to work.

 

The blade on the left is 1.5mm thick and its angle is about 45°, the right hand one is 1mm thick and the  angle about 30°.  

 

I am reluctant to try to hone the blades without comment from anyone who thinks this would be successful or can suggest another method.
