The Breitling Emergency is a battery-operated watch with a built-in microtransmitter with broadcasting capability of 121.5 MHz aircraft emergency frequency. In the event of a crash or emergency, the watch’s transmitter can be activated by unscrewing a protective cap and pulling out the antenna. A signal is then broadcasted for up to 48 hours for rescuers to home in on. The signal has a range of approximately 160 kilometers for an aircraft flying at 6,000 meters.
