I have this on the bench to investigate an issue with the chrono seconds hand. It’s quite a nice watch, dating from 1983, and has held up well as the dial is in excellent condition and the case is well worn but still nice and sharp. Here’s a shot as it arrived. After cleaning around the caseback with a pegwood stick and a brush, it’s removed to get a look at the movement. All looks fine from a distance but inspection with a 4X loupe made me reach for the microscope. A closer view showed that the movement was in need of a service, there is dried oil on the jewels and the pivots in the bushings are lubricated with I don’t know what. A couple of the jewels, one dried out, one with "bits" on it. Some of the bushings. This one has dried grease. This one has dried out "something". As does this one. And this one has an extra little bit. There is also a sliver of metal evident, not good in an electronic (or any) watch. The pushers and tubes also have some gunk and rust, but that’s to be expected after so long being used as a tool and not a safe queen.
