The Seiko Astron GPS Solar 2026 Limited Edition (ref. ssj039j1) is a quartz gmt watch, with a 41.2mm titanium case, 12mm thick, powered by the 3X62 movement. Water resistance is rated to 100m, under a sapphire crystal. Manufacturer MSRP is $2,400.
The Seiko Astron GPS Solar 2026 Limited Edition is noted for its advanced GPS timekeeping that automatically updates time and date via satellite signals, powered by light to eliminate battery changes. Owners appreciate its design and texture, and the legible dial despite its complexity, with one owner preferring its less overloaded appearance over other Astron models. However, the GPS function requires a clear outdoor line-of-sight to the sky for reception, which can be an issue indoors or in dense urban environments, and DST is not implemented. The watch is priced over $2,000, and while it features a perpetual calendar, it only displays the date. Overall, owners and reviewers find the Seiko Astron GPS Solar 2026 Limited Edition a functional and appealing watch, particularly for its automatic timekeeping and solar power, though its GPS reception limitations and price point are noted considerations.
