Just wondering...is there ever a situation in which the mainspring slips and will not hold the power?
I have a VR 3185 in an ARF 116710. I have added a gen jumping hour date module, hour wheel, date jumper spring and date wheel. When I wind it manually, I can see an amplitude of 280 - 290, or more, but I never see more than 250 - 260 otherwise.
I have installed a genuine 145 winding module. Still the same. When I manually turn the winding rotor I can see that it is winding the mainspring. Additionally, the rotor is turning freely and with no interference. Thus the question. The only other denominator is the mainspring. If it had too much braking grease or not enough, might it slip enough to lose some power.
Also...sometimes when I wind it manually, it will have a high amplitude immediately, but in a few minutes it might be back down in the 240s to 250s. The watch has not been serviced.
Thanks for any consideration.
