I figured I could regulate a ETA2801-2 (which the H-50 is based off), having some experience with ETA and Seiko movements. Lately my Hamilton Khaki Pilot Pioneer has been running slow 15s per day which is unacceptable in my opinion for such a new watch (it was doing +2s per day when I got it 3 months earlier).
I opened up the back and to my surprise it looks like a free sprung movement. I really don't want send the watch away but I'll have to because I don't know how one regulate a free sprung movement with out taking the balance wheel out.
So I'm hoping someone on the forums has had some experience with the H-50 movement, any suggestions or pointers?
