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 Bronze

The Tudor Black Bay Bronze is widely praised for its unique, evolving aesthetic due to its bronze case that develops a pleasing patina over time, with owners finding this gradual aging process incrementally pleasurable and ideal for summer wear. Reviewers highlight its robust construction, in-house MT5601 movement with a 70-hour power reserve and excellent accuracy, with one source reporting it losing about one second every three days. The 43mm case size is noted as being larger than other Black Bay models, and while some find it surprisingly comfortable and well-proportioned with its Arabic numerals, others consider it too large and bold for daily wear under a suit cuff, with the bronze case deemed less smart than steel. The matte brown dial with an explorer-style layout and gilt snowflake hands are also frequently mentioned features. One owner specifically praised the bezel's feel as the best on the market, though another reviewer found the dial numerals and lume weak.
