You land in Dubai at 2 a.m., switch your phone out of flight mode and glance down at your wrist. The time is already right. That small, quiet moment is what Seiko Astron GPS Solar was built for.
Launched in 2012 as the world's first GPS solar watch, it remains one of the most advanced Seiko watches ever made. The Astron reads the time from satellites and draws its power from light, so there is no fumbling with settings in a hotel room and no routine battery change before the next trip.
In this guide, we look at how the technology works, where it began, and whether it is worth the price. Then we walk you through six Seiko Astron models at Circa, from the 2024 debut of Calibre 5X83 to two numbered limited editions.
Seiko Astron GPS Solar is Seiko's line of watches that set their own time and time zone using GPS satellites and run entirely on light. It debuted in 2012 as the world's first GPS solar watch.
The latest models use Calibre 5X83, which adds dual time and a chronograph, and stay within ±15 seconds a month even without a GPS signal.

The world’s first GPS solar watch. By connecting to the GPS network, the Astron adjusts at the touch of a button to your time zone and, by taking all the energy it needs from light...
The Astron name has always meant "first" at Seiko. On 25 December 1969, the Quartz Astron became the world's first quartz wristwatch. More than four decades later, Seiko gave the name to another first, a watch that takes its time from space and its energy from light. If you're still deciding on the brand itself, our watch buying guide is a good place to start.

Three ideas sit inside every Seiko Astron GPS Solar: satellites for the time, light for the power, and a movement clever enough to manage both. Here's how they fit together.
When the dial senses sunlight, the watch connects to the GPS network on its own, up to twice a day, and corrects itself to the second. Land somewhere new and one press of a button finds your time zone.
The dial turns natural or indoor light into energy and stores it, so the watch keeps going long after it leaves the sun. Our guide on how a solar watch works explains the basics.
Introduced in 2024, Calibre 5X83 was the first Astron GPS Solar movement to pair Dual-Time with a chronograph.

Yes, especially if you travel often. A Seiko Astron GPS Solar sets its own time by satellite, runs on light and stays within ±15 seconds a month without GPS, all in a light titanium case.
A fully charged Seiko Astron GPS Solar runs for about 6 months, or about 2 years in power-save mode. With regular light and proper care, a Seiko solar watch can keep going for many years.
At Circa, Seiko Astron GPS Solar watches start at INR 2,50,000 for the SSJ014J1. The 5X83 Dual-Time Chronographs, including the two 2025 limited editions, range up to INR 3,20,000 in our edit.
Yes. A Seiko Astron GPS Solar receives GPS satellite signals anywhere in the world, including India, and sets India Standard Time automatically once it has a clear, open view of the sky.
Seiko Astron gave the world its first quartz wristwatch in 1969 and its first GPS solar watch in 2012. Today, Seiko Astron GPS Solar sets itself by satellite and runs entirely on light.
The original Seiko Quartz Astron of 1969 sold for 450,000 yen in an 18-karat gold case, about the price of a mid-sized car then. Today's Seiko Astron GPS Solar carries that pioneering spirit.
Most Seiko Astron GPS Solar watches are regular production, but Seiko also releases limited editions. At Circa, the SSH183J1 and SSH185J1 are 2025 limited editions of 1,200 pieces each.
