If you are getting + a couple or seconds or minus then just leave your watch overnight:
(a) flat on its back to add a second or so;
(b) crown up or down to lose a second or so;
This way you can regulate it without having to make any manual adjustment. However, note that the watch can change after a while so you may have to go from (a) to (b) or vice versa.

Rolex has been advising customers about this for decades.

Enjoy!!

Exactly!

In this timing run pic below I use nighttime resting position to regulate the watch. Tonight will be crown up to lose time to nudge it back to the 0 line.

Funny thing is I really don't care at all about my watch running a few seconds here and there. I like the game / challenge of interacting with it to try to hit zero.

I bought a new DJ41 in Aug 2020 from an Ad. For the first few months, ran consistently at -3.6 to -4.0 sec per day. Now, it seems to be speeding up, I've been measuring -3.0 sec per day for the last month. Wearing it all day, resting dial up at night. Some days/nights, it speeds up to -2 sec a day, it seems to do this at a certain point in the power reserve? I periodically wind it up, or maybe have an active day with a lot of wrist movement so maybe this has something to do with it? Have yet to run the power reserve down as it has been on my wrist every day but may try it.
BTW, I'm not obsessing over this, I do have a life, I just do a quick check with the Watchtracker app while having my morning coffee, I find it interesting. Enjoy this site and everyone's comments!

My masterpiece is running 6 seconds slow over 3 weeks I think that’s amazing!

Related to this thread---just wanted to put in a plug for the free Tg timegrapher software. (Easy enough to Google.) I'll admit I was a little skeptical at first, especially when the first read on my watch showed it being -16 seconds or so/day when I know for a fact it's closer to -2. (This was less about me testing my watch and more about me testing the software.) But then I saw the instructions for calibration, using a quartz watch, and after doing that setup (which took a little while and required a very quiet room), the software is just awesome. Using my PC's microphone, can get a very cool graph readout, and was able to confirm that my 126610 is indeed -2s/day. It's not a professional-grade timegrapher, obviously, but is better than any of the smartphone apps I've played with.

I'm receiving a vintage Omega tomorrow and plan to check it first thing. It's not an expensive piece, so I may even experiment with regulating it myself if needed.
