What people say

Owners + reviewers, side by side

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

Oris Big Crown Diamonds

Owners widely praise the Oris Big Crown Diamonds for its timeless design, vintage charm, and recognizable details like cathedral hands and the pointer date function. Reviewers highlight the stunning gradient dial and the "Bullseye" tuxedo dial as particularly beautiful. The 38mm case is considered versatile, and the watch offers remarkable value. However, some owners note the standard Sellita movement has a short power reserve and plain finishing, and the strap is not durable. A reviewer points out slightly imperfect Super-LumiNova printing on the hour numerals, and one owner finds the two-tone bracelet overly flashy. On balance, owners and reviewers rate the Oris Big Crown Diamonds highly for its unique design and value at its price point.

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
