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.

Vario 1918 SG60 Merlion Trench

The Vario 1918 SG60 Merlion Trench is widely seen as a commemorative keepsake, particularly for those celebrating Singapore's 60th anniversary or born in 1965. Reviewers note its vibrant red enamel dial and 37mm steel case with fixed wire lugs, along with 100m water resistance. One owner reported the watch is "patina-ing well" after three years, and the Miyota 82S5 movement is considered a reliable, cost-effective base. Overall, owners and reviewers appreciate the Vario 1918 SG60 Merlion Trench as a unique souvenir and tribute piece, with its distinctive enamel dial being a key draw.
