Breitling Second Generation Emergency Help Watch-world’s First Dual Frequency Positioning Beacon Emergency Help Watch

The Emergency II emergency watch II was developed by Breitling in cooperation with large scientific research institutions. It has attracted much attention for its many innovations in the field of microelectronics and microtechnology, including The watch was developed with three configurations: a revolutionary rechargeable battery, a miniature dual-band transmitter, and a new built-in antenna system.
In 1995, Breitling launched the first watch with a built-in miniature emergency distress signal transmitter, which caused a strong response. The emergency help watch (Emergency) is fixed on the international aviation distress emergency call frequency of 121.5 MHz, which can guide rescuers to determine the pilot or passenger’s call for help in the event of an aircraft crash. This watch is designed to be worn on the wrist for a long time and complements the standard configuration on board the aircraft.

The Emergency II watch uses the Global Satellite Search and Rescue System satellite network, which also includes a ground receiving station and a control and coordination center. Its mission is to provide accurate and reliable distress signals and positioning data to assist search and rescue (SAR) agencies in rescuing people in distress. The Cospas-Sarsat Global Satellite Search and Rescue System has saved more than 26,000 lives since it began operations in 1985.
The innovative dual-frequency transmitter means that the second-generation emergency watch is based on the special requirements of the Cospas-Sarsat global satellite search and rescue system. It is equipped with a miniature transmitter that can send two different frequency signals for 24 hours. It can first send a digital alarm signal to the satellite at a frequency of 406 MHz with a duration of 0.44 seconds and an interval of 50 seconds; then it can send an analog signal that can guide positioning and rescue at a frequency of 121.5 MHz with a duration of 0.75 seconds and an interval of 2.25 seconds.

The wearer only needs to unscrew and pull out the main antenna protection cover on the right side of the case to activate the system. Once the two antennas are deployed, simply place the watch in a suitable place to ensure the best transmission performance. A compact device with a built-in new antenna system, the transmitter can use part of the antenna, or both antennas. This is an unprecedented technology in the area of ​​distress beacons. The new rechargeable battery specifically designed for this emergency watch is also a technological miracle.
Energy supply is crucial in the development of the second-generation emergency watch. The Cospas-Sarsat global satellite search and rescue system requires beacons to ensure that signals are transmitted for 24 hours. In addition to the duration requirement, the particularity of the dual-frequency transmitter must be considered, and the power levels of its alternate operation are very different (the power at 121.5 MHz is 30 mW, and the power at 406 MHz is 3.2 W, which is the former 100 times), this feature requires a certain current consumption. Not to mention that all components must be fully built into small watches. Therefore, Breitling designed a new rechargeable battery for this emergency watch. In order to ensure the reliable performance of the second-generation emergency watch, Breitling also developed a charger tester that can periodically charge the battery and automatically check whether the transmitter is operating normally.
The case of this watch is made of titanium, the preferred aerospace industry, and is equipped with an observatory-certified super quartz movement.
