It is, without doubt, no exaggeration to say that the Seiko Quartz Astron with caliber number 5X53, released December 25, 1969, was a wristwatch that changed the world. With 100 times the accuracy of a standard mechanical watch, it was the watch that began the democratization of the quartz movement that would eventually bring accurate timekeeping within the reach of all. Non-stop, always accurate, and beautiful
The Second Revolution,
The second-generation Seiko Astron is a GPS solar wristwatch that was released in 2012. While the new Astron has functions and capabilities that far exceed those of its 1969 predecessor, the name Astron was chosen to demonstrate the importance of the GPS Solar technology that it contained and to highlight its high accuracy which was just as revolutionary as that of the first Quartz Astron. The “new” Astron released in 2012. It was the world’s first mass-production wristwatch with time synchronization by GPS satellite signal reception and time zone adjustment functions. Efforts thereafter went into making the Seiko Astron smaller and improving the reception performance and interface.
