Launched in 1952, the Navitimer once again proves its ability to stay one step ahead of the rest by revisiting one of the most demanding watchmaking complications: the split-seconds chronograph. Entirely developed and produced in the firm’s workshops, its Manufacture Breitling calibre B03 introduces two major patented innovations. The first stems from the key challenge raised by the construction of such a chronograph: energy. Breitling has developed an innovative system serving to isolate the split-seconds hand so as to avoid its starting and stopping phases generating variable energy requirements liable to be detrimental to chronometric precision and reduce the power reserve. The second patent relates to the mechanism for stopping the split-seconds hand. Inspired by cycle brakes, Breitling has wrapped the traditionally used wheel with an O-ring seal that compresses the clamp, thereby ensuring extremely precise stopping and greater reliability.
