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.

Seestern S456 GMT

Owners widely praise the Seestern S456 GMT for its exceptional value and finishing that exceeds expectations, with one owner noting its accuracy surpasses that of their Seiko 5. The dial displays a pearl-like rainbow effect. Some owners would prefer a bidirectional bezel over the current unidirectional one. The Seestern S456 GMT features an NH34 movement, a 39.5mm case, sapphire crystal, and an adjustable clasp. On balance, owners rate the Seestern S456 GMT highly for its impressive finishing and value proposition at its price point.
