I did end up winning the auction, although at a price that was closer to my bid limit than I would have liked. The watch in question has a 14k gold-filled case with an engraving on the back -- characteristics that I figured would be a turn-off for most prospective buyers. The photos were appalling in quality, which made the purchase feel riskier than it needed to be. But, the deed is done and the watch ended up being much more attractive in appearance than the eBay photos suggested.

I actually found this engraving to be a positive feature of the watch, adding some interesting provenance. And since this watch was found in the midst of a birth-year watch search, having that year engraved on the watch is pretty cool. Even the name "Jones" appears in the engraving! (but I'm not related to that particular Jones, to the best of my knowledge).
