Breitling Navitimer B01 Chronograph 41 Blue Dial Black Leather Strap Watch for Men AB0139241C1P1 Menopausia WomanLog. Breitlings iconic pilots chronograph for the journey. In 1952, Willy Breitling developed a wrist worn chronograph with a circular slide rule that would allow pilots to perform all necessary flight calculations. Two years later, the Aircraft Owners and Pilots Association (AOPA) announced the design as its official timepiece. The navigation timer or Navitimer was born. The AOPA was (and remains) the largest pilots club in the world, counting nearly every US aviator among its ranks. As the defacto pilots watch throughout the glory days of civil aviation, the Navitimer was worn by airline captains and aircraft enthusiasts. It even made its way into space on the wrist of astronaut Scott Carpenter in 1962. And it wasnt only pilots drawn to the watchs irrepressible aesthetic. Celebrities of the day such as Miles Davis and Serge Gainsbourg were devotees, proving that the Navitimer had style as well as function. There have been many iterations of Breitlings icon since its debut 70 years ago, but this new Navitimer captures its most classic features, while enhancing them with modern refinements. A flattened slide rule and a domed crystal create the illusion of a sleeker profile. Alternating polished and brushed metal elements give a lustrous, yet understated finish. Most notably, new colors in shades of blue, green and copper, define the updated dial options. And if there is one update sure to spark nostalgia, its the return of the AOPA wings to their original position at 12 oclock. For 70 years, Breitlings original pilots watch has been beloved by aviators and tastemakers in equal measure. Worn by astronauts in space and the biggest stars on earth, it is Breitlings most iconic timepiece and one of the most recognizable watches of all time. Brushed & polished stainless steel case.
