This was very interesting, excluding the three or four commercial interruptions, because I've got one of these that doesn't work. Nobody really repairs these because a new movement can be had for less than twenty bucks. I saw one of the motor armatures it stuck to a magnet during reassembly. Then I found the other one. It looks like one motor drives the hour hand and date, and the other the minutes and seconds.Very useful. Thanks for the posting of this video.
I have a JS50 with no chrono operation but I could reset the second hand after battery change. Is my battery just low? It wasn't working at all until I pulled the battery for a week.
