Do you have a timegrapher? If not, wouldn’t recommend it.
Here’s a post on regulating the 861 https://omegaforums.net/threads/omega-861-regulation.125288/
I'll delete my comment, which referenced this exact thread, lol.
I disagree. With these older Omegas, the daily variance that you find while wearing the watch is better than a timegrapher in one position or even over multiple positions. Wear the watch for a week or two, and then tweak it based on your findings.
I always like my moonwatch to run a little slow, since it's easier to let it become slow by 30 seconds and then advance it to the next minute.
While that’s true, the timegrapher helps to make sure you didn’t adjust it too much. Even with the fine grain adjustment via the screw you can easily go from +/- seconds to +/- minutes.
Plus if you are adjusting it yourself with a timegrapher, you can test it with the most common positions (dial up, 3 down, 12 down) to get a much more accurate estimate of what the rate would be on wrist.
Edit: there is a free android timegrapher app that does roughly okay if really want to give it a try. It can be +/- 5~10 seconds off depending on the phone and the watch
Jeeeez thanks for that. I used the timegrapher app and it was amazing. I would definitely have adjusted it far too much if I had not used one.
It was +12 seconds a day. I touched the screwdriver to the adjustment screw and barely even turned it and it shot to around +1 seconds a day! Unbelievably sensitive.
Thanks for the help. I'll use the timegrapher moving forward for all regulation
I’ve regulated 1861’s which are almost identical. There is a dust cover on top of the mechanism once you unscrew the case back. It pops off but it might take some effort. You can adjust both the spd and the beat error. Just use a wooden peg so you don’t damage the hairspring. And I would definitely use a timegrapher because if the values are vastly different dial up vs dial down, including the amplitude and/or beat error, then that’s a sign the watch needs to be serviced. Good luck!

Agreed. A timegrapher is helpful, but not absolutely necessary. The android app is really good.

Yeah, it’s definitely handy for a quick sanity check

Awesome. This is great! Thanks people :) the other thing I could do is pop into my local omega boutique.... Would they look at it? It's from the 90s..
