The Emergency II is equipped with a microtransmitter alternately operating on two separate frequencies over a 24-hour period. It transmits a first digital signal on the 406 MHz frequency intended for satellites and lasting 0.44 seconds every 50 seconds; as well as a second analog signal on the 121.5 MHz homing and rescue frequency, lasting 0.75 seconds every 2.25 seconds.
The development of this dual frequency transmitter specifically designed for the Emergency II was a major technical challenge, essentially due to its dimensions that had to be adapted to the wrist. Conducted in cooperation with an institute specializing in aerospace, defense and industry, it notably involved creating a new circuit exclusively dedicated to this instrument in order to be able to transmit on two frequencies and to do so within an extremely compact volume.
The result is a record in terms of both miniaturization and guaranteed reliability, which lays down new benchmarks reaching well beyond the sphere of watchmaking. (more)
About US$18,600.00, if you go for the titanium bracelet instead of a rubber strap.
