Jeez, that watch is generic looking.
In fact, I have one that looks just like it.
My grandfathers watch was gold-filled however not 18 carat gold but otherwise it looks identical.
Sounds like you have something to pass down and cherish for your family when you teach little ones about their history and tell them the stories they’ll remember when they, in their turn, take out your watch. That’s a perfect sort of family keepsake.
