Oldie but goodie!

I purchased this Omega a couple of years ago. At that time it was fully serviced and regulated to within +/- 2 sec/day by the watchmaker. Now in reality it had always ran on average minus 1-2 sec/day.. still within spec and very accurate. Well the slow rate always kind of bugged me a tad.. so yesterday I decided to regulate it to a positive rate. I know I know who cares?! And Why?! It was already running really good ya muppet!

Well I've regulated nearly ever watch I own to be as close, on avg, to 0 sec/day but always slightly fast versus slow. -- I'd rather be early than late!

After 24 hours post regulation, my time grapher readings in 5 positions were.. +0 +0 +0 +0 +1 which as a point in time gives an avg rate of +0.6 sec/day rate. The beat error was already pretty good but improves slightly the better the rate is.

Now opening the back of a watch just to look at the gorgeous movement is not unheard of but figured while I was in there I'd regulate the rate and check the gasket and relubricate it 😁

If you've read this far you know the rest of this post was just the excuse to see the movement 😁

I wouldn't dare even open the caseback on such a watch 😁

Will opening the caseback break its water resistance?

Sure.. unless you know how to properly reinstall the case back and gasket. It's fairly simple though. I also checked gasket for any wear or damage then applied a fresh coat of silicon grease before reinstalling in the case again. Then it's just a matter of screwing the case back down tightly - many tools to help here ofcourse.
