Well... You guys got me inspired. You may be onto something with this "404 club" thing. I've been casually trolling eBay the past few evenings, and thought I'd give it a shot. I converted £4.04 to USD ($4.94), and started tossing around throwaway "Best Offer(s)". I actually scored one, and not even one but seven! A lot of 6 identical, and a seventh very very similar watches with 17J manual wind movements. They look like the cases are silver plated (no photos of where any telling marks might be found, so I'm going with plated) and thoroughly tarnished. What's more, they look mostly NOS and unworn; some still have bits of sticker on the back. No idea what the movement is, but I figure if I can't get at least most of them up and running and sold to make a few bucks for the next "404 club" buy, I'm doing something very very wrong.
Yes ithink you are right as a contrast to the stainless steel a nice dark blue would be perfect. The good thing id if you dont like it you can always clean it off. There used to be a chemical used for blueing gun barrels that would make a nice dark metalic blue.
