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.

Yema Flygraf CPA10

Owners widely praise the Yema Flygraf CPA10 for its light 40mm titanium case, slim 9.4mm profile, and excellent legibility on its blue brushed dial with applied Super-LumiNova markers. The Yema CMM.10 automatic movement is considered terrific, offering chronometric precision of -3/+5 seconds per day and a 70-hour power reserve. Some owners appreciate the aluminum warranty card and packaging as nice touches. The watch is priced at €1,690. One owner noted concerns about the long-term reliability of older in-house movements due to mixed origins, though praised customer service under new management. Overall, owners rate the Yema Flygraf CPA10 highly for its comfortable wearability and attractive, legible dial design.
