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 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.
