I have actually had this for years, but totally forgotten about it. It was my great-grandfather's watch and is engraved as such.
A couple of questions, if anyone knows the answer:
1) How is the acrylic/glass attached? It seems to be just a push fit, but it has popped out once and doesn't seem 100% secure. Is there a recommended method of re-attachment?
2) The crown pulls out very easily, and so it's easy to stop the watch by accident. Is that a usual issue?
I have been tracking its timekeeping over the last couple of days and it's within a few seconds each day, so I'm very happy with that. I'll definitely keep and use it if it is. When I first tried this, it seemed to stop every minute at around 18:25. I finally figured out that the hour hand was catching on the second hand! So I carefully bent it upwards a little and that's fixed the problem.
