Rolex 3035 Issue

[rattandsonwatchmakers]

I am having an issue with a rolex 3035...cleaned..oiled...fresh mainspring....rotor spins freely on the auto bridge...I attach the auto bridge and rotor to the movement...rotor spins freely...until I tighten the auto bridge screws...then I feel quite a bit of resistance in the rotor spin...loosen the screws and away it goes again...tighten the screws and slows down....what could be causing this to happen....thanks...

check to see is there is a broken pivot in the jewel hole, or maybe a misaligned/bent axel/pivot? hope this helps.

Sounds like an alignment issue. Was it free before you stripped it down?

I am ashamed to say that I did not check. I do see rotor friction burn on the plates and it appears that the rotor axle has been changed. The watch I was told had been sitting in a drawer for several years. I did find that it had a broken mainspring

In his tutorial on servicing the 2824, Marc said that when putting back the automatic bridge you should give the stem a half turn to allow the wratched wheel to engage with the automatic gears.. It's very unlikely to make this mistake, but I think you should check.

I reassembled the auto wind mechanism. and all is in good working order...thanks for all your advice
