I did a search and did not come up with anything, so I was wondering if anyone had any possible answers. I bought a Mido Multifort about 3 weeks ago. It is a Powermatic 80, yet when I take it off for a couple of days I have noticed it dies. My other Powermatic does not do this. It can sit over 3 days. Is there something wrong? This is the 3rd or 4th time it has died after 2 days. It runs fine and generally keeps time at about +3 seconds a day. There were a couple of times I may not have been active enough because I was on planes travelling, so that could account for some of it, but I wore it to work Tuesday and I am generally quite active. I had just gotten back after being off for an extended period, so I was very busy that day and running around a lot. Do I need to fully wind it? If so, every time? I have hand wound it, but I do not do it every time. I hand wind intermittently, but not every time when it comes to my automatics and have never had any issues.
