Hamilton introduced the Accumatic line in 1956 and produced them in various versions through 1972. This particular model was called the Accumatic A-514 when first introduced in 1972. In 1973, Hamilton dropped the Accumatic branding and this watch was known just as the A-514 in its second, and final, year of production. This watch comes with a Swiss made (ETA) Hamilton caliber 818 automatic movement with 17 jewels. The watch features a mint condition matte finished green dial with applied hour markers with black accents and a painted minute track on the white chapter ring. The stainless steel case has been hand polished with fine scratches evident. On the original band with Extension.
