OHMYGODITSAPANERAI 0 Posted June 26, 2010 I have an A7750 in an IWC that is having a problem. If you wind the watch, set the time and let it run it will stop after only a few seconds/minutes. If you wind it, set it and start the chrono the watch will run and even keep accurate time BUT the chrono second hand will only move occasionally (if at all). I have opened it up, but cannot see anything odd with the balance assembly. Any suggestions? Share this post Link to post Share on other sites

OHMYGODITSAPANERAI 0 Posted June 26, 2010 Found it. Broken oscillating pinion. The top post was broken allowing the gear to wobble and jamb the seconds wheel. Share this post Link to post Share on other sites
