I'd like to buy my wife a solid yellow gold wristwatch with a leather strap, in a tank style. I am not keen on quartz - I was thinking a vintage manual wind model. Does anyone know where I would have the most luck looking for this sort of thing? Most of the watches on eBay don't fit the bill, and those that do are ugly. There are a few Cartiers that do the trick, but very few are solid gold, and those that are tend to be very expensive. Ideas? Dealers? Any help is appreciated.
