The Breitling Emergency version contains a radio transmitter for civil aviation use which broadcasts on the 121.5 MHz distress frequency and serves as a back-up for ELT-type airborne beacons. (For military users, Breitling has equipped the Emergency with a miniaturized transmitter operating on the 243 MHz military frequency.) Under normal conditions—flat terrain or calm seas—the signal can be picked up at a range of up to 90 nautical miles (167 km) by search aircraft flying at 20,000 feet (6,000 m). As of 1 February 2009, the Cospas-Sarsat Satellite System will no longer monitor the 121.5/243 MHz frequency; however, the signal transmitted by the Emergency was never strong enough to be picked up by satellite, and Breitling has announced that, as these frequencies will still be monitored by aviation, particularly during the localization phase of a rescue attempt, there are no plans to modify the signal's frequency.
You have to sign papers when you buy this watch stating that you are responsible for a false distress signal and will pay the massive fine.
