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.

Bremont Supernova

The Bremont Supernova is praised for its new ENG375 movement, big date, and power reserve indicator, with its 40mm steel case featuring mixed finishing and an integrated bracelet. Owners note good but not great lume, well-balanced proportions, and a premium feel for its price, despite a 173-gram weight. Some community members find the design derivative and the £8,000 price tag overly optimistic, with mixed views on the date window and crown guard. The proprietary Trip-Tick case construction offers shock protection, and the movement provides a 65-hour power reserve. Overall, owners and reviewers highlight the integrated bracelet and proprietary movement as key strengths of the Bremont Supernova.
