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 Automatic Diver Watch

Owners widely praise the CWC E9 Automatic Diver Watch for its military-spec toughness and satisfyingly easy-to-wind crown, with one owner calling it a perfect reissue due to its thin case, small size, and legibility. Some owners appreciate its durability and value as a beater or summer watch, noting its solid bars are a military requirement and highlighting its significant wrist presence and unique "Jolly Roger" dial design. Critics find the CWC E9 Automatic Diver Watch overpriced for its mineral crystal and 60-click bezel, despite its military heritage and HAQ movement, and its luminous paint is noted as low glow. Overall, owners rate the CWC E9 Automatic Diver Watch highly for its military-spec toughness and wrist presence, despite some reservations about its value proposition.

Hamilton Jazzmaster Auto Chrono

Owners widely praise the Hamilton Jazzmaster Auto Chrono for its excellent value, blend of classy and sporty design, and detailed dial with applied markers. The watch is noted for its impressive accuracy, with figures ranging from +0.5 to +3 seconds per day. Its 42mm case is described as a classic size with a mix of polished and brushed finishes, and the reverse panda dial is a particular highlight for some. However, the lume is consistently criticized as fading quickly and being underwhelming, and the internal bezel's functionality is found to be cumbersome. One owner found the watch too formal for their needs, while another noted the square case can wear larger than some alternatives. Overall, owners rate the Hamilton Jazzmaster Auto Chrono highly for its exceptional value and attractive, accurate timekeeping.

From video reviewers

The watch features a quality automatic chronograph movement. The date setting mechanism, requiring a specialized pusher tool, is a notable drawback. Reviewers disagreed on whether the watch competes effectively with luxury alternatives at its price point.
