How it works

The Satellite Timekeeping System allows our watches to set the correct time and date by receiving time signals from GPS satellites orbiting 20,000 kilometres above the earth.

Precise timekeeping anywhere on earth

With coverage across 40 of the existing UTC standard time zones, watches with Satellite Wave will ensure the most accurate time you will find in any conventional watch. Whether you trek through the desert, cruise the oceans or climb a snowy mountain, you never need to worry about having the correct time.

Worlds fastest satellite time reception at 3 seconds*

Satellite Wave technology allows your watch to adjust to a new time zone with amazing speed and ease. Receiving a satellite signal in as little as three seconds, Satellite Wave has the world’s fastest signal reception speed from GPS satellites.
