Seiko Astron was our’s and the world’s first quartz watch. This revolutionary watch was launched on Christmas Day of 1969. It was different from the other watches of that time because it was the first that ran on batteries instead of gears.
Many decades later, the Astron evolved and changed watchmaking again. In 2012, Astron became the world’s first GPS solar watch. The GPS solar technology it uses allows it to connect to the GPS network to adjust to the time zone with a touch of a button.
The decision to use a GPS network for telling standard time came from learning that only four countries in the world that send out standard time signals. That means the data from satellite stations aren’t as accurate as a GPS network, which enables Astron to tell time accurately regardless of your location. It also takes all the energy it needs from light, thus eliminating the need for a battery change.
Elevating the GPS solar watch technology is the newest addition to the Astron line, the Astron 5X Series. It’s equipped with a completely new caliber with high-speed time zone adjustment and a time transfer function capability. Every component in its GPS module has been re-engineered to enhance the quality and speed of the GPS connection, allowing it to change from one time zone to another as fast as three seconds.
Its time transfer function enables simple and instant switching of home and destination times between the main and sub-dial. By pressing the buttons at two and four o’clock, the Caliber 5X changes the main display and sub-dial from local to home time and vice-versa. Astron 5X also adjusts automatically to the exact time up to twice a day by connecting with one or more GPS satellites. It also remembers the last time it successfully received a time signal and automatically attempts to receive one.
