GenTLe Posted January 17, 2015 Report Posted January 17, 2015 Guys, I have a BP factory watch that has a movement (1st one I ever tried to service) that has an oscillating amplitude: it goes from 250 (+8s/d) to 221 (-11s/d). What the heck does this mean? Bad gears that do more resistance in single points? Is it fixable? Thanks, GenTLe
Rolexman Posted January 17, 2015 Report Posted January 17, 2015 If the amp. jumps all over the place without switching the position of the movement it is probably magnetised.
GenTLe Posted January 17, 2015 Author Report Posted January 17, 2015 Well it's time to get a demagnetizer so. The amplitude oscillation goes in cycles of around 2 minutes, if this can say something more...
kbh Posted January 17, 2015 Report Posted January 17, 2015 Could it be a slight bend in one wheel of the gear train. Every time it goes around it gets more resistance at a single point.
