same here, already tried 3-4 times with no success, mine is +7,7 s/mo
it's a pain so I am not so willing to try again
the only AD Longines service here refused to play with it, and I will take it to another guy, I hope he knows about adjusting and has the tools
my 8F32 Seiko is -25,5 s/y for 43 days on my wrist

Assistant tool for calibration.....I made this, not pretty, but usable!:-!

contact points are not where the wires in the button are, if we look at the picture in the manual
how do you know where to fix them

After using the button method (thanks vizi, saved me a lot of nerve cells) for adjusting my VHP, it is +0,008 s/3days (2 off 1 on wrist). It will need more time to be conclusive for the success of the adjustment. I used 23 taps to leave it fast instead of 24.

Good to hear but how did you measure 0,007 seconds ?!

I don't know if it is exact but monday i made 2 video clips and the watch was -0,275 s (mean), today again 5 clips -0,267 s, sorry 0,008 s

yes, some times the hand is caught in transit but i note the frame when the hand hits the mark so that it is consistent with the other clips
anyway, the difference is obvious, this time the adjustment seems to have worked

I adjusted my VHP on 15/3/2010 with 23 taps and today it shows +2,3 spy, on-wrist, I guess it works
sad I had to reset my 8F32 for summer time, it was -24 spy from 29/1/2010
I will leave it until next DST change, on and off, and then maybe try pattern cutting (not very sure about that though)

the shirt button saved me
