Repair of Heuer Autavia Calibre 12. This watch had a problem. The watch was running
fine and “happy ticking” but it lost time and couple oh hours on a day. I have a main rule while doing repairs and overhauls, that is always try to find the issue and what is causing the problem before total dissasembly. In this particullar movement the friction in hand setting mechanism was totally gone. That resulted in fine movement running but without bringing along the hands.
