Breitling, which has produced many masterpieces in close partnership with the aviation industry, established its position as a pilot’s watch with the development of the two chronograph buttons (start/stop at 2 o’clock and reset at 4 o’clock) in 1934, the prototype of the current chronograph, and the world’s first rotating slide rule in 1942. The development of the world’s first rotary slide rule in 1942 established the company’s position as a pilot’s watch. While pursuing its own path as an independent brand not belonging to a major conglomerate, Breitling has recently introduced an environmentally friendly watch box, and we cannot take our eyes off of Breitling’s trends.
