The Hamilton Martin was one of the Hamilton Watch Company’s most popular pre-war models. The Martin was one of Hamilton’s last models before turning their production to the war effort. The watch is powered by Hamilton’s pre-war workhorse, the 17 jewel 987A movement, serial number 0205432. This is a highly reliable and sturdy movement and actually went on to become one of the mainstays of wartime watch production. The case is 10K Rose gold filled, front and back. This is a Wadsworth case, manufactured specifically for Hamilton.  The case number is H551943.  It is smaller by today's standards but still suitable for a woman or a man.  The Case measures approximately 1" square.  The watch is running and kept good time for 24 hours.  The dial and case both show wear from use, but it also gives it a very cool vintage patina.  It is currently on a vintage JB Champion twist o flex style bracelet. Â
