There are countless watch factories and their classic watches that make flying watches, such as Longines Lindbergh series, which is famous for imitating early pilots' watches, Pilot, which has the world's professional military flying watch set, Graham Chronofighter and Bell & etc. Ross watch series, Polaroid and Rolex originally designed Oyster Perpetual GMT-Master II for civil aviation pilots, while Hamilton's khaki X-copter was even designed for helicopter pilots. However, Breitling is still very popular with pilots. The emergency described in 1988 has a miniature waterproof transmitter at the bottom of its watch. In the temperature range from -20℃ to-100℃, it can send out two pulse signals every minute at the frequency of 12 1.5 MHz, and the transmission scale is160. This design enables Emergency to be widely used for emergency rescue in aviation, diving, mountaineering, exploration and other activities, so that rescuers can determine the location of objects in distress in time. Of course, the more classic Breitling should belong to professional aviation timekeeping such as Navitimer. By rolling its outer circle, the pilot can quickly do general multiplication, division, proportional operation, and even root sign conversion. The most practical calculation in flight is navigation-including flight time, speed, interval, fuel consumption rate, fuel demand, cruise remaining time, and calculation performance such as climb height, climb rate and climb time.
