I am embarrassed to admit that I really don't know as much about it as I should -- I don't even know what the "dwarf hand" is (the hour hand? . I purchased it when I was in high school and was seriously into diving (daily for several months/yr over 3 years) -- right around 1970 or so. I saved like crazy (cleaning sailboat hulls) be able to afford it, and yes, it was that cool orange face that hooked my teenage self on it.
The serial number is 28799-4, then on the line below is "6675087". I'd be most grateful for any insights anyone has about that era of Doxa.
And I must admit that I feel a bit guilty that it isn't in the care of a a serious collector. I of course will now keep it wound, but am not even sure I will-- or should-- wear it much. Instead of a stop-watch, I need a watch that displays multiple timezones, and thus have a rolex explorer II as my everyday watch.
