38 mm steel case, three hands, dark dial with light colored numbers, triangular indexes with Super-LumiNova® of a similar color to the previous ones on the radio, sturdy NATO strap: the new Khaki Field Mechanical is a faithful reproduction of its predecessor of the 1960s and fits perfectly into Hamilton's military tradition. The authentic military watch now sports a 'Terra' colored PVD case, an exclusive prerogative of Hamilton. The H-50 is an exclusive caliber specially developed for our manual winding watches. The H-50 is available with or without a date function and has an extended power reserve of up to 80 hours, ensuring maximum reliability even when the watch is not worn for a few days.
