My father gave me his grandfather's railroad watch. We're not sure of the exact age of the watch. A few questions:
1. I'm told it works, but I haven't wound it. I assume it should be serviced first? (Or should I leave it alone?)
2. My father would like the glass replaced. Will this decrease the value?
3. Any idea of the age or value? The face looks dirty, but that's just the glass. The face is immaculate as far as I can tell.
