I'm not going to say a single bad thing about Waltham. The reason they aren't rare is the same reason Singer sewing machines aren't rare - they run forever and unless someone is actively buying them up and destroying them, they'll still be serviceable when the sun is a cinder. The thing that gets most of them is they get pawned, the cases get melted down and the dials and movements end up in someone's drawer, 300 at a time. Case looks like it's in great shape! Rolex is pretty easy to suss out, too. There's a very real trend these days to leave them completely unmolested and that guy looks to be in pretty good shape. I'm going to guess inter-war, and it's probably worth $2-3k US. Most collectors like the dials left alone but they wouldn't look down on the lume being reapplied to the minute hand. How's the band holding up? That's something you should look into; the rest of the watch won't suffer from being in a drawer forever but old leather (of all critters) can dry out and die.
