The Breitling Emergency II Replica Watches

The original Breitling Emergency, introduced in 1995, was the first wristwatch with a built-in emergency microtransmitter. Designed to enable accurate homing in on pilots or passengers following a plane crash, it operated on the 121.5 MHz international air distress frequency. Pilots prized it for its utility: it could be worn constantly on the wrist and serve as a supplement to standard onboard aircraft equipment. Around 40,000 Breitling Emergency watches have been sold since their launch. The Breitling Emergency II represents the next generation of its predecessor’s life-saving microtechnology. The very first wristwatch equipped with a built-in personal locator beacon, its dual frequency transmitter is compliant with the specifications of the Cospas-Sarsat international satellite alert system and can be used both to issue alerts and to guide search-and-rescue missions.

Breitling developed the Emergency II in conjunction with major scientific institutes, and the Cheap Breitling Replica includes three innovative new features developed specifically for it, including a new rechargeable battery, a miniaturized dual frequency transmitter and an unprecedented integrated antenna system. With the integration of these microelectronic and microtechnical inventions, Breitling set out to create “a safety and survival instrument in all distress situations on land, at sea and in the air.”

The international Cospas-Sarsat system, whose mission is to provide accurate and reliable distress alert and homing data, uses a network of satellites in low-altitude earth orbit and in geostationary orbit as well as ground receiving stations and control and coordination centers. Search-and-rescue teams use this information to assist persons in distress; since its launch in 1985, the system has helped save more than 26,000 lives. Up until 2009, Cospas-Sarsat used the 121.5 MHz analog frequency for the Breitling Replica alert and homing phases of the rescue process. That year, it decided to phase out the 121.5 MHz frequency and began receiving alert signals on the new, digital 406 MHz frequency instead, to provide better security and to reduce the number of false alarms. Hence the need for a new Emergency watch that complied with the new satellite frequency. Making matters a bit more complicated, the 121.5 MHz frequency is still used on land, by ships at sea and by airborne aircraft, so modern distress beacons must offer dual frequencies for the most accurate homing.

Breitling accepted the challenge with the invention of its microtransmitter PLB, which alternately operates on two separate frequencies over a 24-hour period. The watch first transmits a digital signal on the 406 MHz frequency, intended for satellites and lasting 0.44 seconds every 50 seconds, then an analog signal on the 121.5 MHz homing and rescue frequency, lasting 0.75 seconds every 2.25 seconds. To accomplish this task, Breitling Replica Watches worked with an institute that developed technology for the aerospace and defense industries to create the watch’s ingenious antenna system, with two miniature antenna sections housed in the lower part of the watch and activated by a knob in the lower right side of the case. To deploy the antenna, which automatically activates the transmitter, you unscrew and pull out the knob’s cap. The cap automatically comes free of the antenna when it is deployed to the right length, at which point the cap of the second section of the antenna is automatically released. The antenna length varies according to the wavelength; depending on the circumstances, the transmitter uses either one antenna section or both; this is a first for a locator beacon.

Breitling also had to address the issue of energy and durability to meet Cospas-Sarsat’s standards, which demand that beacons must be capable of transmitting for up to 24 hours and at temperatures as low as -20 degrees Celsius. Also, the antenna’s two frequencies operate at vastly different power levels: the 121.5 MHz signal at 30 milliwatts and the 406 MHz signal at 5 watts, 170 times higher. In collaboration with another industrial partner, Breitling developed a brand-new, robust rechargeable battery created specifically for the watch. Each Breitling Emergency II Replica Watches is, in fact, delivered with a charger-tester device to periodically recharge the battery and check the operation of the transmitter.
