    • I guess it is a possibility, but the train wheel bridge was pressed down all the way so I'm not so sure. Then again, the screws weren't tightened at all (imagine being screwed down all the way but using a piece of Rodico instead of a screwdriver). Anyway, the movement is now fully stripped so we'll have to see once I've assembled it again. BTW I found the post where @nickelsilver wrote about tightening screws: As he writes: "In school, if your screws aren't tight, like you think they might snap, you get your movement tossed in the sawdust box!" I'm really curious to know why it is so important to tighten the screws that hard. I usually stop when it feels like there is no chance the screw can start to unscrew itself. Also, screwing down that hard requires perfectly dressed and perfectly sized screwdrivers to avoid slippage and/or damaging the screw slot.
    • This place has them, cheaper than I saw on ebay and they appear to be a legitimate supplier: https://maddisonsofdurham.co.uk/watch-parts/capacitors/seiko-batteries-capacitors/seiko-capacitor-kinetic-30235mz-tc920s-5m42-5m22-5m23-battery-3023-5mz-3023-5my/?gad_source=1&gclid=CjwKCAjw7-SvBhB6EiwAwYdCASmviGb9G2ZGW3CtcUZBkNgglcgfPKoqnpOzrzruiPtm69f6DX7UGhoCKl4QAvD_BwE There is also a note at the bottom of the page about them being a newer type, with a slightly different part number.  
    • Are we ignoring  that another watch on tg showed similar rate fluctuation. Did I miss any conclusion made on this sigificant  point ?    Springs have high fatigue threshold,   meaning angle of  bend/distortion  has to be very sharp to cause material fatigue .  An evidence to this point is the bend we form at end of terminal curve or the bend at the collet,  are we causing fatigue there? definately not.       
    • Yes, I do have the Seitz pivot gauge which is worth a small fortune these days. Got mine for about £200 which I thought to be crazy expensive at the time, but I've now seen asking prices over twice that. And no, I do not have the scaled pin gauge, but it would be convenient. Let me know if you find them! Anyway, the Seitz pivot gauge is in my opinion not really necessary if you have the JKA Feintaster. It can measure even the very small pivots w/o making any dents. One will have to be a lot more careful when using the Bergeon micrometres.
    • Update. Ran into a winding problem since some desperate previous repair guy had fitted the wrong winding gear. Cousins had one ! Turns out the movement is the slightly different 022 - 18 Looks like the one LH screw fixing for the crown wheel got updated to the two screw style.
