It works by reading the top bezel against the bottom scale printed around the dial to perform various calculations such as fuel consumption and climbing speed. The Slide Rule has become less essential to professional pilots with the invention of the modern calculator but it is still as sought-after as ever. Part of the watch’s massive appeal lies in the distinctive aesthetic the Slide Rule and chronograph add to the watch. Additionally this series exudes the contemporary elegance often associated with Breitling – one of the most sought-after luxury brands on the market.
