Breitling Old Navitimer - Full Set

Breitling Old Navitimer automatic chronograph. It was originally purchased from authorised Breitling dealers in 1992. It comes complete with all boxes and papers including the slide rule instructions, warranty booklet. The Navitimer was first introduced in 1952, the Navitimer provided pilots and air crews with a highly innovative chronograph design.

These include: multiplication, division, calculating ground speed, calculating miles per hour, calculating miles per minute, calculating fuel consumption, calculating rate of climb or descent, calculating the distance of climb or descent and nautical and statute mile conversion. This is a true professional instrument watch that has been adapted to today's even more strenuous requirements. Comes on original black leather strap with a wear to it and Breitling pin buckle. The leatherette coating to the box is showing deterioration where the paper Breitling wallet has adhered to it.
