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 U1 S L

The Sinn U1 S L is widely praised for its intense, full-lume dial, a feature described as new technology that glows brightly, and its unique black and white "arctic tactical" aesthetic. Owners and reviewers consistently highlight the Tegimented German submarine steel case for its exceptional scratch resistance and matte, non-reflective finish, with one owner reporting no scratches on the case after 17 years. The watch is also noted for its legibility and robust build, offering 1000m water resistance. However, some owners find the 44mm size and 14.7mm thickness wear large, and one reviewer noted the 4 o'clock crown positions lacked distinct clicks, leading to difficult date changes. Accuracy figures for the ETA 2824-2 movement vary, with one owner seeing +1/+2 s/day and another about -6 s/day. The Tegimented bracelet is reported to scratch more easily than the case by some, while others found it held up well.
