http://www.ebay.com/itm/Mens-Breitling-Emergency-Mission-18k-White-Gold-Quartz-Watch-/181351648176?pt=Wristwatches&hash=item2a39668bb0This watch is a pilot or traveler’s best friend, should one become lost without hope of escape. On the bottom-right side of the case is an Emergency Assistance Transmitter. By twisting off the cap, a 121.5 MHz emergency transmission will be broadcast for up to 48 hours, and will reach an emergency vehicle up to 90 miles away in clear conditions. If a plane is flying within this radius at 20,000 feet, the transmission can also be picked up.
WARNING: If you use the emergency transmitter function, you will be subject to whatever charges the Coast Guard or any other rescue organizations see fit.
