Reaches every place in the world.

Works in all 40 time zones
The range of CITIZEN Satellite Wave GPS covers all 40 time zones of the world. * The Satellite Wave technology receives
GPS satellites orbiting the Earth at an altitude of 20,000 kilometers to determine the correct time and positional data.
Time to display your exact location. In the desert, on a snow-capped mountain top or in the middle of the mountain.
Sea, you can get the correct current time for each location.
The range in the time zones can vary from model to model.

Synchronizes to the time of the place you are at.

Precise and accurate time, wherever you are
Imagine driving across a continent like Australia or the United States, where you have multiple time zones in the
the course of your journey. Wherever you go, Satellite Wave GPS synchronizes with GPS satellites at the touch of a button,
to acquire position data and a time signal. It uses this data to find out in which time zone you are in.
and synchronizes your clock to the correct time of your current location. Even if you are using multiple
Time zones, you can always be sure that your watch displays the correct local time.
*Some models only receive time signals.
*Determination of position data requires at least 30 seconds. The changeover to summer time must be done manually.

Just 3 seconds for the time. 30 seconds for place and time.

The signals sent by GPS satellites are based on a total grid, which in turn is divided into five partial grids.
With Satellite Wave, you can choose whether you want to receive “Position data and time signal” or “Time signal only”. * To
to receive both position data and a time signal, you need all data from the overall grid. This requires at least
30 seconds. In order to receive only the time signal, at least one partial grid is theoretically generated in a time period of 6 seconds.
required. Because our Satellite Wave technology is able to calculate the correct time based on only the first 1.2 seconds of a 1.2 second satellite wave.
Partial grids, it only takes three seconds (including the time needed to find the GPS satellites),
to get the correct time. CITIZEN is the only company in the world to offer this fast synchronization time of
has reached three seconds.
*Some models only receive time signals.

    I love this watch. Just a bit sad that a small speck of the black finish around the crystal chipped so easily 🙁

    Just had it for three weeks but can’t make up my mind if I should try to get it fixed at the dealership somehow.

    I have had this watch since 2017 and haven’t even looked at another watch since. It is lightweight, durable, the lume on the hands is excellent and lasts all night long, and the GPS time ensures the watch is always correct to the second, and keeps up with my frequent business travel. And it looks great as my daily driver and as a dress watch.

    I travel (or, rather did and will eventually do again) travel all over the world for business, and this watch is an invaluable travel companion.

    It has the time correct to the second before I reach the air terminal. The alarm is loud enough to wake me from the deepest sleep. It is always correct to the second, it is amazingly light for its size, thanks to the titanium case and bracelet, and it looks as good as when I bought it, five years ago.

    It’s a reliable daily driver and a stylish dress watch.

    Came across this watch in 2016 and was super impressed. Somehow forgot about it over time. Came across it again a month ago, spent a month researching features and competition. This came on out as the clear winner, finally found a dealer shipping to Singapore. Loving it since day 1! After a few syncs the time seemed to be off by 5 seconds, figured out the leap second correction function and now its back to its accurate self. Love love love it! Technological masterpiece, fits well on my 6.5′ wrist, great design and finish that goes well with anything I wear.
