The Patek Philippe Naviquartz timepieces were originally meant for use on ships and yachts, but quickly became a status symbol for one’s desk. The refs. 1207 and 1208 were made from 1972 through the mid-1980s. The only difference between this and the ref. 1208 is the dial color.
This is a near perfect specimen example complete with its original key, certificate of origin, and mahogany outer box.
