I finally figured out what the (+) and (-) really meant. Logic told me at first that you move the lever to the right to speed it up (+), and to the left if you wanted to slow it down (-). But the opposite resulted!!! :-[

It actually meant that if your watch is running too fast (+), move the lever to the right; and if it is running too slow, move the lever to the left.

Now I got it spot on! ;)

Of course you also change the effective length of the main spring , by moving that lever, so it will result in an faster or slower running watch, but you will very likely see the watch running less stable.
You use this lever normally, to ensure that when the balance wheel is not moving, the pallet stone is in one line with the center of the anchor and the center of the balance.
In trivia: it regulates the difference between the "tick" and the "tack" of a watch, which is ideally zero (if you imagine a running watch sounding tick-tack-tick-tack...).

Cheers,

Axel

P.S. perhaps one of the native speakers can explain it better

You got lucky (very lucky, if you don't own a timegrapher). The idea is you put the watch on the machine and get the bph correct, then fine-tune with the regulator (if you can call it that, with Seiko's notoriously touchy regulator).

Are you serious, I moved the wrong lever?? :eek:
But it's right on the dot now! Right to the second!!!

Before I messed with it, it was running at -45 sec/ 24 hrs. After this "lucky" regulation, it is now at +4 sec/ 24 hrs. (against the atomic clock) and holding steady. I don't know about you but +4 sec/day is sure a lot better that -45 sec/day! ;)

Have you checked the positional variance, sometimes a watch that is out of beat will run fine sitting flat but once you start checking in different postions the timekeeping can go way off. hope it's not the case, but should be checked face up, face down, crown up etc. hope you got lucky

Lucky enough ... I wear it to work by day, and lay it face up by night. Same routine everyday and it still maintains +4 sec/day. I am quite happy with it being in the COSC standard range now.

Regulating was done on the Silver 6139! This time on the right lever! Before adjustment, it was running at -12 sec/ 24 hrs. I've only moved it a tad bit towards the (+). I use a loupe when I do this to clearly see the displacement. The displacement made was only as thick as my hair! :eek: And now it is running at a constant +4 sec/ 24 hrs. Now within COSC standard!

Am I good or what?!! :)
