[j.e.t.]

+1 on this. I obtained an new SKX007 late last year, which was stable at approximately -17 a day. After having it regulated approximately 2 weeks ago, and even while doing various positional tests overnight, it has lost only 9 seconds in the 10 days that I've been monitoring it! It loses a few seconds a day while I wear it and gains them back resting (to varying degrees depending on position). But it will be even more accurate once I have determined what all the positional effects are on the watch of course. Needless to say I'm very pleased with the result of the regulation...
