Breitling - 'Navitimer Montbrillant Datora' - Column...

Welcome to my Top Swiss Chronograps Boutique! Breitling S.A. was founded in 1884 by Léon Breitling. It's known for precision-made chronometers designed for aviators. In 1952, Willy Breitling was approached by the world’s largest pilots’ club, the Aircraft Owners and Pilots Association (AOPA), and asked to create a new chronograph for its members. His answer was the Navitimer—a wrist-worn instrument that would enable pilots to perform all necessary flight calculations, including average speed, distance traveled, fuel consumption, rate of climb or descent, and conversion of miles to kilometers or nautical miles. At that time, all these calculations required a logarithmic slide rule. To create it, Willy adapted the original logarithmic slide rule of the 1940s Chronomat for aviation purposes and integrated it into a rotating bezel, surrounded by small beads to make it easier to manipulate. At 41mm, the case was unusually large for the time, ensuring maximum legibility. Oversized Arabic numerals coated with luminescent radium provided excellent contrast against the black dial. The name “Navitimer”—a combination of “navigation” and “timer”—perfectly captured the essence of the pilot’s tool watch. The original version designed for AOPA bore no Breitling branding on the dial and was exclusively distributed to AOPA members. In late 1955, the Navitimer was released to the public with the Breitling name and a stylized winged logo distinct from the AOPA version. In the late 1960s, watch wearers had to choose between an automatic watch and a chronograph, but no one had yet found a way to put the two together. To overcome this challenge, Breitling began the ambitious and visionary development of creating one of the first automatic mechanical chronograph calibers. Developed in partnership with Heuer-Leonidas and Hamilton-Buren and Dubois-Depraz, the Breitling Chrono-matic was launched on March 3, 1969 offering two timepieces in one, a mechanical automatic watch and a chronograph—changing watchmaking history forever. For over 70 years, the Navitimer has been beloved by aviators and tastemakers in equal measure. Worn by an astronaut in space and the biggest stars on Earth, it is Breitling’s most iconic timepiece. Once a tool for charting a pilot's course, now a companion for all those plotting their personal journeys through life.
