Plus-Minus-Plus-Minus - ARGGGH!

[Geeeyejo]

Been playing with the Asian 21J movement in my Cartier Santos 100 Rep tonight. After two days wear was running about 1 minute 20 sec slow per day - opened the case (8 TINY screws DAMN) and proceeded to play with the adjuster - SOB, no "plus" or "minus" markings on this one and a "mirror" copy of the visable movement in my Baume & Mercier (ie adjuster on the other side) Well, tried it a small nudge down - hacked the movement, checked it 30 minutes later and even SLOWER - a nudge up and too fast - down again, too slow - thought I had it right replaced the 8 screws and too slow - opened again and too fast - ARRGGGHH - think I may have it right now and won't replace the caseback until correct - maybe the bottle and 1/2 of Shiraz isn't helping, lol...
