Emergency Beacon Watch

as highlighted by Izwan 9W2IZW,

This is good for Hamsters that get lost in the jungle,
or over water.
The watch in question transmits an emergency signal on
either VHF or UHF distress frequencies of
121.5 Mz or 243 Mz.

121.5 MHz transmitter power reserve at 30 mW : 48 hrs

243 MHz transmitter power reserve at 25 mW : 24 hrs

Thermal operating range : –10° to 85°C.

Transmitter water resistance : to 30 m (3 atm)

Transmitter power source : 2 x 3V independent lithium batteries.

water-resistant to 30 m (3 atm). Sapphire crystal, glareproofed front and back.

Incorporating an emergency microtransmitter, the Breitling Emergency was developed to assist pilots in distress.

The Emergency version for civil-aviation use 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 with On/Off switch, operating on the 243 MHz military frequency.

Under normal conditions — flat terrain or calm seas — the Emergency's signal will be picked up at a range of up to 90 nautical miles by search aircraft flying at 20, 000 feet.
The Emergency is designed to foil any handling mistakes and to protect the transmitter from even violent jarring.
