This watch has been in my family for a while, and its story is pretty classic. I'm Finnish, and a branch of my family tree ended up migrating to the US in the 19th century. Some eventually came back, and one who had been a train dispatcher brought this watch with him.
I just had it repaired and cleaned, so now it runs perfectly again and looks great.
Looks like this one.

Could be? The hands look slightly different (especially the minute hand which isn't "solid" in mine) and that one doesn't have the inner 24h circle on it though, but I have no idea if those differences are significant
