OW - SELECTRON V7733

Price N/A

At the express request of the aeronautical sector, since OW had resumed the manufacturing of the Breitling Navitimer in 1979, it was able to integrate a similar Selectron calculator on its new chronograph model. The ability to make precise short-term measurements allows for an increased number of operations, making it an indispensable tool for airline pilots who constantly need to check numbers and make conversions. For example, it makes it possible to reliably calculate speed (in miles per hour), gasoline consumption, the rate of climb or descent, and even convert distances in nautical miles.
