·Working on an Omega cal. 1012 and I’m chasing a weird hand-setting issue.
With the pallet fork removed, everything functions normally. Winding works, quickset date works, and the hands can be set normally in the third crown position. I did have to replace set lever as it was worn beyond use, However, while setting the hands, the going train is being driven strongly all the way through to the escape wheel in both directions.
As soon as I install the pallet fork, winding and quickset still work, but I cannot turn the crown to set the hands in the third position. When I try, I can physically see the escape wheel loading/pushing against the pallet fork and the train locks.
So basically, hand-setting is back-driving the entire train, and once the pallet is installed the escapement becomes the hard stop.
Have any of you run into this on a 1012 before? I’m trying to figure out where the hand-setting friction/slip is supposed to occur on this caliber and what could be seized or assembled incorrectly.
Greatly appreciate your collective minds. I can provide pictures and try to get a video of it if needed.
