Seiko Astron GPS Solar 3X62 titanium silver dial titanium bracelet 42 mm

Astron Heritage — Quartz Pioneer in the Space Age

When Seiko introduced the Astron in 1969, it revolutionized global watchmaking by unveiling the world’s first quartz wristwatch.
In 2012, the brand reshaped the industry once again with the first GPS Solar watch capable of synchronizing with satellites.

The Seiko Astron SSJ037J1 embodies this spirit of continuous innovation: a traditional analog watch equipped with cutting-edge technology that automatically adjusts the time anywhere on the planet.

It is not merely precise.
It communicates with space.

GPS Solar Technology — Exact Time, Anywhere in the World

At the heart of the SSJ037J1 beats the 3X62 GPS Solar calibre, an advanced electronic movement capable of receiving satellite signals to determine:

• The exact time
• The time zone
• The correct date
• Adjustments linked to the perpetual calendar

In practice, when traveling, a simple activation of synchronization allows the watch to detect your location and automatically adjust to local time.

No manual setting.
No approximation.

Powered by Light

Solar technology enables the watch to recharge through both natural and artificial light.

It offers up to 6 months of autonomy on a full charge without additional exposure.
Unlike a smartwatch, it:

• Requires no daily charging
• Does not depend on a smartphone
• Does not become obsolete

It is high technology… yet timeless.

A Lightweight and Ultra-Resistant Titanium Case

The SSJ037J1 features a titanium case, a material renowned for:

• Its lightness
• Its corrosion resistance
• Its wearing comfort

It benefits from Seiko’s proprietary Super-Hard Coating, enhancing scratch resistance.

With a 42 mm diameter and only 12 mm thickness, the watch remains remarkably slim considering the technology it houses.

A sapphire crystal protects the dial, while 100 meters of water resistance ensures everyday versatility.

A Controlled Sci-Fi Aesthetic

This limited edition draws inspiration from science-fiction universes and futuristic representations of space stations.

The dial plays with:

• Structured textures
• Metallic contrasts
• A deliberately technical depth

Despite its electronic sophistication, the SSJ037J1 maintains clear and elegant readability, staying true to Seiko’s analog DNA.

An Integrated Perpetual Calendar

The watch incorporates an electronic perpetual calendar, programmed to automatically manage:

• Short months
• Leap years
• Date transitions

Once set, it requires no manual correction for decades.
