Positions affecting readings

If I could find the Bergeon part numbers I'd be on my way over there now!

Lucky for me it's only in the old print catalog. I think for safety reasons they removed it from the online so you'll have to find somebody with one of the older catalogs. Then there probably won't take your order again for safety reasons.

Timekeeping specifications are always interesting and now that people have nifty timing machines that are affordable amplitude is now number one at least on the discussion groups.

Then timing things PDF is attached with how to do all the nifty calculations if you really want to get obsessed with nifty calculations. It's so much nicer feel the timing machine that does this for you but typically there very expensive especially if the microphone rotates around to all the various positions.

Here is an image out of a vintage timing machine manual for timing specifications. Notice no amplitude as cheap timing machines that measured amplitude did not exist. That's also why you cannot find listings of lift angles for vintage watches unless somebody today measured that which is easy to do because they didn't have a nifty timing machine that could do amplitude

Then while some of the Swiss companies do have timing specifications for their watch most of them are Swatch group which means you'd not going to see the entire sheet at the best you might see a snippet. In the case of Omega I think almost all the watches have been time except they do have a generic category. So this would basically be timing for a nice all of the watchThen of minor amusement depending upon which version  in other words they kept updating this the Stabilization and measurement time seems to very. With no problem with their longer if you go too short on these you can end up with timing issues. Like moving the microphone really fast and not allowing it time to stabilize that will be an issue and usually if you run the timing in a position longer things will stabilize and be better plus of course you can change the averaging time in the machine to longer time interval to smooth things out.

Thanks for sharing! I have noticed that leaving it in each position for about 2 min seems to stabilize and provide a better read. I think I’ll just change the reading time on the machine itself. Thanks!

Just closing the loop on this thread with readings post 24 hours (on what I believe is a 30 hour power reserve).  My wife wore it al day and it has worked fine. The amplitude has dropped as expected. The rates are above the factory specs, and in dial up it’s above what many experts suggest as the minimum for a healthy vintage watch (210 degrees). It’s not great, but having re cleaned and re oiled as meticulously as possible, I feel like I’ve run out of ideas. So I’ll leave it at this for now, considering this was technically my first watch service/restoration. I have a few more vintage watches on the bench at present, so maybe I’ll come back to this one after some months of practice and experience if my wife has complaints with its functioning. Thank you everyone for your excellent suggestions and advice! I truly appreciate it! And I look forward to talking with you over the other watches I intend on servicing.
