I have thrown the book at a 10cracd mvmt that stops ,usually pretty quickly, when turned dial up. Appears to be an M4 President ‘I’ . Two tone face. Serviced the watch and it runs well in all positions except dial up. Tried repeating end stone oiling, mainspring service, shimming the Barrel bridge, a spare working balance assembly, and tinkered ad nauseum. At times, after loosening a screw or nudging a bridge it, will run dial up for hours and look good on time grapher etc. Figure problem solved and THEN.......the next cycle is back to its’ old ways. I finally just said ‘uncle’ and put a 10coacd mvmt in the case. I prefer that movement for the beat adjust feature anyhow. But still..... Anything inherent about the 10cracd mvmt being prone to this? Still makes no sense to me. Hate to be defeated. Thanks.
