Shockingly, my solution seems to be coming from the USA! I found a recently serviced Waltham watch on Ebay, and WOW is it a looker! It's 10k gold plated, not solid, but according to the seller (with good feedback and a history of selling such pieces) the watch is 111 years old, so if the plating is still holding up, I'm not concerned at all.
The only thing that it doesn't have is a see-through caseback, but that's to be expected (Are there people who do that aftermarket?) Anyways, the price would be about 340 shipped, which is beyond reasonable, certainly considering what a calatrava or JLC Gentilhomme would cost. And just look at that pretty face!!! :D
Am I missing anything, or should I bite?
