Good afternoon I have an old Rotary wristwatch that has an AS 1950/51 movement. The watch was old and dirty when I got it at a car boot sale. It would run but roughly and due to time constraints I never had time to work on it and clean it up and service it. I have finally got around to stripping it down fully and have ultrasonically cleaned and have lubricated it all and it is all back together but it doesn't run. Well I say it doesn't run it does but not properly. When you wind the watch the escape wheel and pallets kick into life immediately and with the hands on the second hands sweeps around non stop until the mainspring is unwound but the minute and the hour hands do not move. The minute and hour hands move freely when you pull the crown out to set the watch and there is no binding whatsoever. I remember that when I stripped the watch down I noticed that the small cannon pinion that is part of the keyless works drive was friction fitted and took a good pull to remove it but the minute cannon pinion was not and it came away easily. I read that some watches have friction fit cannon pinions and some do not and rely purely on friction grease as used on automatic watch mainsprings to allow them to grip the barrel wall. I have cleaned the minute cannon pinion again and applied some friction grease to it and rebuild the lower end but alas same thing again. Does anyone know if the minute cannon pinion is a friction fit on this movement or if it is friction grease that drives it? I am at a loss as I am so near yet so far to having the movement back in it's case and being able to enjoy wearing it. Many thanks Andy
