50TH ANNIVERSARY Quartz-Astron

A tribute to a watchmaking revolution. The 50th anniversary of the Quartz Astron is celebrated in a limited edition GPS Solar watch.

On the fiftieth anniversary of the original Quartz Astron, a new creation in the Astron GPS Solar collection pays tribute to its celebrated predecessor and brings together the two revolutionary advances in watchmaking history that share the Astron name.

About Quartz Astron 35SQ

On December 25 fifty years ago, Seiko introduced the world’s first quartz wristwatch. It was a watch that revolutionized the watchmaking industry and its launch remains one of the most important landmarks in Seiko’s history. The Quartz Astron set a new standard in wristwatch precision with an accuracy rate of +-5 seconds per month, made possible by several technological advances including the tuning fork shaped quartz oscillator and the open type step motor which are still standard components of quartz watches today. Soon after the launch of the Quartz Astron, Seiko opened most of its patents to the world, a move that helped bring the advantages of quartz timekeeping within the reach of all. In 2004, the Quartz Astron received the IEEE Milestone Award for its breakthrough contribution which is today widely used not only in horology but also in a vast range of other electronic applications. The Seiko Quartz Astron is recognized as one of Japan’s greatest achievements, giving all mankind access to high precision timekeeping and changing the way time was told around the world.

GPS Solar Seiko Astron

The Astron name was revived in 2012 when the world’s first GPS solar watch was launched. Like its predecessor, the Astron GPS Solar took electronic watchmaking to new levels with its ability to connect to the GPS network and adjust to every time zone at the touch of a button while taking all the energy it needed from light, never needing a battery change.


Homage to 1969 Quartz Astron

A tribute to the 1969 Quartz Astron

This new limited edition watch brings back to life the form and design of the 1969 Quartz Astron in its entirety. Both the elegance of the celebrated timepiece and its characteristically futuristic feel are reflected in the curved silhouette of the case, the wide case lugs and the thin bezel.

The spirit of the 1969 Astron is reflected in every aspect of the design

Like the 1969 watch, the case is in 18K yellow gold with each delicately hand carved by the highest skilled craftsmen and women. The dial has a subtle vertical hairline pattern and the hands and multi-faceted indexes are thin and carry a black line on the surface, just as on the first Quartz Astron.

The letters “Limited Edition” and the serial number 01/50-50/50 are inscribed on the case back as proof of this limited quantity edition. * In an actual product, the case back direction might be different from the photograph.

Technology of Astron

A new GPS Solar caliber 3X22 The limited edition watch houses a new GPS Solar movement that allows it to have the slimness and grace of the 1969 watch’s form. The new Caliber 3X22 is the world’s thinnest* GPS solar caliber to be fitted in a watch case and is made possible by the highest level of modern watchmaking technology.
Reduced to its essentials of time adjustment and timekeeping, the watch connects automatically up to twice a day to the GPS network to maintain its precision of one second every 100,000 years, and when time zone adjustment is required, with a simple push of a single button, the hands move faster than ever thanks to the system that moves each hand independently.*As of October, 2019, based on Seiko's research.
