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.

Sinn U2 S (EZM 5)

The Sinn U2 S (EZM 5) features good, solid lume that remains readable throughout the night, though some owners find its initial brightness less intense than other dive watches. Reviewers highlight its excellent legibility due to a high-contrast dial and large hands, housed in robust German submarine steel with a scratch-resistant Tegiment-treated bezel. On balance, owners and reviewers appreciate the Sinn U2 S (EZM 5) for its robust construction and clear dial legibility.
