What people say

Owners + reviewers, side by side

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

CWC E9 Quartz Diver Watch

The CWC E9 Quartz Diver Watch is praised for its historical significance, unique Jolly Roger dial, and military-spec build. Owners report it is thin, small, very legible, and has a satisfyingly easy-to-wind crown, with some noting its accuracy and clean lume application. However, the luminous paint on the Jolly Roger is described as low glow, and one owner reported their T20 model had an inaccurate quartz movement and a soft acrylic crystal that scratches easily. Some find the Jolly Roger design "out there," while others like its unique aesthetic. Some feel it is overpriced for its components, particularly the standard Ronda movement. Overall, owners rate the CWC E9 Quartz Diver Watch highly for its unique aesthetic and military-inspired build.

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.
