LONGINES - WITTNAUER A-11

No other clock brand has been involved as much as Longines in the creation on specific machines for pilots and planes, creating more than 100 exclusive pieces.

Ernest Francillon founded Longines in 1866 in Imier, Switzerland.

Albert Charles Wittnauer, that same year introduced in America the brand Longines, in 1880, he created the first line of clocks brand Longines.

In 1912 Emile Wittnauer, in one of the trips to his factories in Switzerland, hired a boy less than 20 years of age called John PV Heinmuller. Soon his great passion for planes was known and Heinmuller   was    nicknamed “Aero 1”.

During the I World War, due to the great knowledge he possessed, he produced a complete range of clocks, altimeters, compasses, turn and bank indicator, situating Wittnauer as one of the first brands delivering quality instrument.

He was promoted to vicepresident, and he collaborated with scientists and characters from that time in the construction of more complex mechanisms, being famous the Longines-Weems clock (Weems was a

great specialist in navigation of the US NAVY), designed exclusively for astronomic navigation. This clock was simplified later by Charles Lindberg and was turned into the more famous clock hour angle, thought to navigate with the Sun and the stars, built by Longines driven by Heinmuller.

In 1928 Wittnauer was the first brand to introduce in USA the waterproof   and

shock resistant clock, and magnetism proof clock. It was used in great dares likelonely flights around the world, conquer of the poles, etc.

Right picture, the Breguet type hairspring, can observed its characteristic turn above the whole spiral, that makes it different for the rest of mainsprings, all plane clocks have it and many wrist clocks too.
