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 2025 Limited Edition

The Seiko Astron GPS Solar 2025 Limited Edition is lauded for its advanced satellite timekeeping and perpetual calendar functionality, offering global time and location updates via GPS signals. Owners appreciate its well-built titanium or steel case, often featuring a ceramic bezel, and the unique asymmetrical design inspired by the 1983 Seiko 7A28 6000. However, its substantial 47mm size and 16.5mm thickness are frequently noted as drawbacks, with some finding it wears large and is difficult to fit under shirt sleeves. The perpetual calendar is limited to displaying only the date, and GPS signal reception requires a clear view of the sky, posing challenges indoors. The watch is priced around $2,900 and is limited to 3,000 pieces. Overall, owners and reviewers value the Seiko Astron GPS Solar 2025 Limited Edition for its cutting-edge technology and distinctive design, despite its considerable dimensions.

Brew Super Metric

Owners widely praise the Brew Super Metric's unique, asymmetrical, and colorful 70s-inspired design, with many appreciating its finishing and dial details for the price. Some owners find the integrated bracelet can be a hair-puller, and the watch wears larger than its 36mm dimensions due to the square case and bracelet. The lume is noted as weak, and some find the dial graphics busy, though others love the colorful, essence-keeping 2.0 design. On balance, owners rate the Brew Super Metric highly for its distinctive style and value, with many finding it a fun and comfortable daily wearer.

From video reviewers

The Brew Super Metric's Meca-Quartz Chrono functionality is one of the best the reviewer has seen. The watch's unique design is a key part of its charm. The Seiko meca-quartz caliber contributes to its value for the price. The lume could be improved, as it's not as bright as some other watches in its class. The price may not be the cheapest option in its class.
