And so can identify it? Comes from another board (here), is the first vintage watch that got me interested, due to the unusual dial graduation. No markings whatsoever. Probably a stopwatch with a 300 * 1/5 sec main scale and 30 min totalizer?Thanks for looking and thanks in advance for any input.Anyone seen one of these before? Came from the estate sale of an ex RN guy. Movement ID? Approx. date?
