Satellite Wave captures position data and a time signal from GPS satellites orbiting in space to automatically adjust time and date. Your GPS watch will display the precise time wherever you are on Earth, as long as there is open sky above you. Satellite Wave needs as little as 3 seconds to receive a time signal only.

Powered by Light It converts any kind of light into energy to power a watch and stores the surplus on a power cell. On a full charge, an Eco-Drive watch runs for months even in darkness with no need for regular battery replacement.

All Citizen Satellite Wave GPS models tell the time with a high level of accuracy of ±5 seconds per month. Citizen was the first watch company in the world to achieve time signal reception as fast as 3 seconds. * We made it possible to reset the time whenever you want; all you need is open sky overhead.

And anti-clockwise to set the minutes of your current time once you are done press the lower right button and now use the crown rotate the crown to set the hour.

Satellite Wave GPS, a unique CITIZEN technology, receives position data and a time signal from orbiting GPS satellites. to automatically update your watch to the correct date and time.

A GPS receiver determines its own location by measuring the time it takes for a signal to arrive at its location from at least four satellites. Because radio waves travel at a constant speed, the receiver can use the time measurements to calculate its distance from each satellite.

A disadvantage might be that an Eco Drive model has to be charged well before its first use. Charging for the first time may take longer, depending on the light source you're using. People often think that these kind of watches are sufficiently charged within 10 minutes in indoor light conditions.

According to reports from Citizen Watches, the solar cells and secondary battery used in Eco-Drive watches will last for up to 10 years. They further stated that the lubricants used in constructing these watches are built to assist with longevity, as the oil will not harden or evaporate, even over 20 years.

The Garmin GPSMAP 66st is at the top of its class in terms of accuracy and reliability, earning it our top honors. It boasts a powerful quad-helix antenna and reliably connects to more satellite networks with greater accuracy than most other models.

Its power reserve may be insufficient. Expose the dial to direct sunlight to charge it. Depending on the model, charging time for a watch to go from stopped to normal operation may vary. Refer to the instruction manual of the watch to verify charge time.
