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 Navygraf Marine Nationale Quartz

Owners praise the Yema Navygraf Marine Nationale Quartz for its well-made case, clean legible dial, and comfortable 39mm size, with one noting its thin profile for 300m water resistance. Accuracy figures vary, with one owner reporting +6 seconds per day and another seeing it keep within COSC time. Minor criticisms include a steel bracelet with a slight rattle and sharp edges, bent bracelet pins, and in one instance, crooked dial printing. On balance, owners find the Yema Navygraf Marine Nationale Quartz offers good value and wearability, with its French design and thinner case being key highlights.
