Transocean Chronograph 1915100th anniversary of a capital invention
One century ago, Breitling created the first independent chronograph pushpiece. To celebrate this milestone invention that was to change the face of the chronograph, the brand is introducing a limited series of its Transocean model, with an exclusive new Manufacture Breitling caliber and an unusual design reinterpreting the famous 1915 pushpiece.
Pocket chronographs had only one pushpiece, housed in the crown and successively handling the start, stop and zero-reset functions. In 1915, Breitling – a specialist in technical watches – was one of the very first brands to offer a wrist chronograph. But in relocating it from the waistcoat pocket to the wrist, the firm introduced an innovation that did not go unnoticed. The founder’s son, Gaston Breitling, came up with the ingenious idea of ensuring a clearer separation of functions by creating a pushpiece independent of the crown to control the three chronograph operations. Keen to ensure smooth, ergonomic handling, he chose to place the pushpiece at 2 o’clock, where the thumb or forefinger naturally rests, whether the watch is on the wrist or held in the palm of the hand. In 1923, Breitling perfected this system by separating the stop/start functions, governed by the pushpiece at 2 o’clock, from the crown-activated zero-resetting. This patented innovation would enable users to add up several successive times without needing to reset the hands to zero – whether timing a sports competition, a scientific process or a flight time. Finally, in 1934, Breitling took the final step in shaping the modern face of the chronograph by creating the second independent pushpiece exclusively intended for zero-resetting. This patented invention was soon adopted by all its competitors.
