What people say

Owners + reviewers, side by side

Synthesized for each watch independently from owner discussions, enthusiast forums, written reviews, and video reviewers.

CWC Automatic Divers Watch Mk.2 Black

Owners widely praise the CWC Automatic Divers Watch Mk.2 Black for its brushed chapter ring, precise 120-click bezel, clear sapphire crystal, excellent case finishing, and significantly improved lume. The watch is considered a terrific value with solid construction. Some owners express a preference for a matte finish for a more tool-like appearance, though polished versions offer a dressier look and easier scratch removal. On balance, owners rate the CWC Automatic Divers Watch Mk.2 Black highly for its tool-like features and excellent value.

From video reviewers

The bezel action is smooth. The price has increased due to popularity.

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.
