I don't do much tinkering with watches anymore since I have Familial (or Essential) Tremor. As the name implies, it causes shaky hands and is passed down from parent to child. Lucky me. Anyway, this Epos watch was bought in 1999 (for a whopping sum at the time of $697) after we'd paid off our house loan. It was a time to celebrate and my wife and I each decided to splurge on something nice. This is what I chose to buy. It had been having minute-counter issues for a number of years. When the chronograph was started, the central seconds hand would go round-and-round as it should but the minute counter would haphazardly either count or not count up the minutes (and since the hour counter was tied to the minute counter, its movement was also intermittent).
I didn't wear the watch much lately because I'd gotten other nicer watches over the years but I pulled the Epos out a few days ago to wear it. That's when I decided to try and fix the problem. It is not a small task to delve into an automatic chronograph movement, and it is compounded immensely by both shaky hands and the fact that this chronograph is additionally complicated with a 24-hour pointer, triple-date (day/date/month) functions and moon phase. I'd watched several videos on YouTube prior to taking the plunge, so I figured I knew pretty much what the problem was and how deep into the watch's bowels I had to go.
