DESIGNATION Mk1 GREENWICH DIVER DEEP BLUE
DESIGNATION MK1 GREENWICH The Designation MK1 Greenwich draws from the birthplace of modern timekeeping. At Greenwich, the Prime Meridian established a reference for global navigation, while John Harrison’s marine chronometer solved the challenge of determining longitude at sea, transforming maritime navigation. That legacy lives on in a modern British dive watch, carrying the coordinates of Greenwich on its dial and paying tribute to the precision, exploration and engineering that helped Britain navigate the world.
