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.

Longines CONQUEST

Owners and reviewers widely praise the Longines CONQUEST for its high-quality finishing, versatile design, and exceptional value, with many highlighting its comfortable wearability and solid build. Accuracy figures are generally positive, with one owner reporting +1/+2 seconds per day. However, several owners note that the bracelet lacks micro-adjustment, which can affect fit, and some find the lume to be weak or inconsistently applied across variants. One owner also mentioned the crown rubbing against the wrist. On balance, owners and reviewers rate the Longines CONQUEST highly for its blend of elegant design and robust build at an accessible price point.

From video reviewers

The perfectly balanced case size is a key strength of the Longines Conquest. A notable weakness is the somewhat lacking lume brightness. Reviewers disagree on the ideal case size, with one preferring 38mm and the other 39mm.
