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.

Tudor Black Bay 58 GMT

The Tudor Black Bay 58 GMT is widely praised for its functional, proportional, and ergonomic design, wearing identically to the standard Black Bay 58 and feeling substantial without being oversized. Owners are very happy with the 39mm case proportions, noting an improved 12.8mm height. The gilt dial aesthetics and gilt-effect accents are a point of praise for some, while others find them divisive. The Tudor Black Bay 58 GMT features the METAS-certified MT5450-U movement, which is anti-magnetic to 15,000 Gauss and offers a 65-hour power reserve. On balance, owners and reviewers rate the Tudor Black Bay 58 GMT highly for its improved case proportions and gilt dial aesthetics.

From video reviewers

The comfortable 39mm case size is a significant strength. The value at its price point is also a shared positive. Reviewers did not reach a consensus on any weaknesses.
