Hi, I'm afraid I am not a clock person or know anything about clocks. I wanted to ask because I have found a travel clock in my grandad's possessions. My grandad didn't really leave much in terms of family objects, and in fact, me and my uncle never knew of this travel clock's existence until a few days ago. We think it might of been my great-grandad's due to how old the travel clock is. Any comments about the clock, regardless of how obvious they are, would be nice. I'd like to know anything more about it since Google fails me. The clock's case is 3.5cm by 3.5cm. The face of the clock has the words "Brook & Son Edinburgh". According to Google, Brook & Son was a family jewellery that ran from 1891-1941 in the city of Edinburgh on 87 George Street. Today 87 George Street is inhabitated by another jeweller, Hamilton & Inches. So with Brook & Son ceasing to exist in 1941 (perhaps the son died in World War II?), I guess that means the clock must be at minimum 76 years old. There is an inscription on the inside of the case, which reads "584 Metal Swiss Made". Another inscription is on the back of the clock, with it reading "546 Metal Swiss Made 218487". I don't know what any of that means I'm afraid. Be interesting to see any light shared on this, even if it is just some mundane obvious facts or speculation on it. I doubt the object has any real worth, but would be nice to keep as a family heirloom. Here are some photos.
