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.

Longines MASTER COLLECTION

The Longines Master Collection is widely praised for its excellent value, with reviewers and owners citing its dressy aesthetic, good fit and finish, and attractive complications like annual calendars and chronographs for under $3,000. Owners highlight the beautiful dials, engraved numerals, and the L893 caliber's 72-hour power reserve. Some find the standard Master Collection thin and well-finished, while others note a slightly thicker case on certain models. A few owners express reservations about the bracelet's adjustment options and the homogeneity of the case finishing. One reviewer points out that the subdial can obscure the '7' numeral on the Small Seconds model, and another notes that pushers can feel cheap and the chrono hour counter may not reset perfectly. Water resistance is noted as 30m on some models.
