What people say

Owners + reviewers, side by side

Synthesized for each watch independently from owner discussions, enthusiast forums, written reviews, and video reviewers.

Seiko Astron GPS Solar 2026 Limited Edition

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.

Yema Yachtingraff Seconde/Seconde/

The Yema Yachtingraff Seconde/Seconde/ is a collaboration watch featuring a hand-painted graffiti-style dial with wet paint drips and spray can pushers, powered by a Seiko VK63 meca-quartz movement. One owner noted slight marks on the lugs, bezel, and case of a pre-owned example, rating its condition at 88%. On balance, reviewers highlight the artistic and humorous blend of design elements as the watch's primary appeal.
