The answer is given within the question, the emergency signals are received by the the International Cospas-SarsatCospas-Sarsat Programme satellites.

From wikipedia:

Space segment

The Cospas-Sarsat system space segment consists of SARR and/or SARP instruments aboard:

Five satellites in polar low-altitude Earth orbit called LEOSARs
Seven satellites in geostationary Earth orbit called GEOSARs
Over 35 satellites in medium-altitude Earth orbit called MEOSARs

From the webside of the watch:

Technical data Beacon Watch

Standard applied COSPAS-SARSAT

C/S beacon classification PLB

Category 2 Transmission frequencies 121.5 MHz / 406.040 MHz

Transmission power ≥ 30 mW @ 121.5 MHz / ≥ 3.2 W @ 406.040 MHz

Transmitter autonomy ≥ 18 hours at –20°C / ≥ 24 hours at +20°C

Operating temperature (beacon) –20°C to +55°C

Power supply Beacon: 1 x Li-ion 4.2 V, 1.1 Ah / Watch: 1 x silver oxide 1.5 V

An article about the watch.

I will extend this answer within the next days.
