A version of this watch was hugely popular with US soldiers during the Vietnam war era, so Hamilton have recreated it. The new Hamilton Khaki Field Mechanical 38mm is inspired by a mid-20th-century model named the Hamilton "Hacked". This comes from the ability of the watch to make the seconds hand stop when the crown is pulled, which enabled military forces to synchronize their watches. It has since become a much sought after feature on most modern timepieces.
