Q
   jump on ebay and nail yourself one of the Russian Railroad watches from
Molniya
No kidding those things are incredibly accurate 18 Jeweled and you can get one under 30 bucks. The were built to handle a drop off a building. Boy they built them. For carry purposes and don't want to mess up a great old antique watch these things are amazing. Just try typing Russian pocket watch in the search .. the railroad ones will come up.
