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 ProPilot Big Date

Owners and reviewers widely praise the Oris Big Crown ProPilot Big Date for its legible dial and comfortable 41mm size, with many noting its sharp, original design suitable for daily wear. Some reviewers flag the 38-hour power reserve as unimpressive for the price and suggest the movement's decoration could be improved, while others point out the "Big Date" complication is misleading and the bracelet lacks micro-adjustment.

Some owners report concerns regarding the movement and warranty process, while a reviewer questioned the value proposition at its price point and noted minor finishing inconsistencies on a prototype. On balance, the Yema Wristmaster Slim Small Seconds CMM.29 is highly regarded by owners for its distinctive design and comfortable wearability.
