Hamilton U.S. Military Issue H3 circa 1980


US Military issue Hamilton man’s wristwatch featuring 34 X 41mm non reflective brushed finish base metal case with screw down case back, acrylic crystal, and original matte black dial with 24 hour indexes and oversize triangular luminous hour indexes, luminous hands and arrow tipped sweep seconds hand. Powered by 7 jewel manual wind calibre 447ST Standard Time Corp (S.T. Co.) non hacking movement. Case back dated September of 1980. With removable spring bars that take an 18mm 2 piece, or 1 piece NATO style strap.

A very good preowned condition example recently fully serviced and in excellent operating condition. With nicely patina’d oversized luminous plots, fully intact luminous wide luminous hands, and without any damage, chipping, nicks or other detractions from the great condition and eye appeal of this piece.

As non military experts, we were intrigued by the H3 and radioactive symbol printed on the dial.
According to our reading, the H3 is an alternative designation to T SWISS T for the low radioactive luminous material tritium. H2 is regular hydrogen, and H3 is a hydrogen isotope. While Britain used the letter T in a circle to designate the use of tritium on their military issue watches, the H designation was used in other European countries. The H3 designation is probably best known on the Heuer Bundeswehr models where it is printed in bold red.
