Seiko Astron Levels Up With Sleek New GPS Solar Dual-Time Chronographs

When you’re chasing time zones or simply chasing greatness, your wrist game matters. Seiko just added 4 new additions to their cutting-edge Astron GPS Solar Dual-Time Chronograph lineup, and let me tell you, these are not your average smart timepieces—they are precision tech wrapped in luxury design.

GPS-Powered Precision Meets Sleek Japanese Engineering

The Astron GPS Solar is Seiko’s flagship for a reason. Since its debut in 2012, it’s been a watch that does it all—adjusting automatically to time zones with GPS connectivity and powered completely by light. Now with their new Caliber 5X83, Seiko brings even more to the table: chronograph functionality, dual-time display, and a case so refined it demands attention.

Each new model connects automatically up to twice per day to the GPS network. And if you’re off the grid, a manual connection is just a button press away. As Seiko explains, “When the dial detects sunlight, the watch connects to the GPS satellite network and adjusts automatically to the correct time.”

Rugged Titanium Meets Luxury Finishing

These new models combine power with polish. The titanium case—lightweight yet tough—is finished with mirror polishing and includes a sapphire crystal insert on the bezel for added finesse. Sub-dials at 12 and 6 o’clock feature diamond-cut markers for enhanced legibility, while the main dial pops with 3D horizontal stripes, a subtle flex that hints at the watch’s technological might.

The multi-row titanium bracelet features both mirror polishing and hairline finishing, blending sport and sophistication. “Manufacturing titanium parts with intricate finishing requires a great deal of expertise as well as advanced manufacturing technologies,” Seiko notes—and it shows.

Three New Colorways for Everyday Elevation

The trio joining the main collection includes:

• SSH175: Blue-gray dial
• SSH177: Gray dial
• SSH179: Black dial with all-black super-hard coating

Whether you’re suiting up or keeping it casual, these pieces are designed to upgrade your look without shouting for attention. Expect availability in May 2025 at Seiko Boutiques and select retailers.

A Limited Edition That Drips Sophistication

If exclusivity is your thing, Seiko’s dropping a limited edition (SSH180) capped at just 1,500 pieces. This one turns heads with rose gold-colored accents, a deep navy dial, and a sapphire crystal bezel paired with a faceted titanium bezel in matching rose gold. Oh, and the center links on the bracelet? Done in lustrous black ceramic for an ultra-premium finish.

“The clean look of the sapphire crystal bezel insert combined with the faceted, rose gold-colored titanium bezel provides a radiant quality to this edition,” says Seiko.
