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.

Rolex Deepsea Challenge

The Rolex Deepsea Challenge is widely recognized as an engineering feat, showcasing Rolex's first all-titanium construction and extreme 11,000m water resistance. Owners and reviewers consistently describe the 50mm Rolex Deepsea Challenge as a massive, gigantic, and barely wearable "monster" of a watch, with some finding its size and proportions impractical and uncomfortable for extended wear. Reviewers note a crude, charred-like brushed finish on the titanium bracelet and dial printing with soft edges and inconsistent spacing, which falls short of the brand's usual high standards. On balance, owners and reviewers view the Rolex Deepsea Challenge as an outstanding technical achievement and a unique collectible piece, rather than a practical daily wearer.
