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.

Sinn U2 S (EZM 5)

The Sinn U2 S (EZM 5) features good, solid lume that remains readable throughout the night, though some owners find its initial brightness less intense than other dive watches. Reviewers highlight its excellent legibility due to a high-contrast dial and large hands, housed in robust German submarine steel with a scratch-resistant Tegiment-treated bezel. On balance, owners and reviewers appreciate the Sinn U2 S (EZM 5) for its robust construction and clear dial legibility.
