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. The cockpit-style clasp is a noted highlight. Overall, owners and reviewers rate the Oris Big Crown ProPilot Big Date highly for its legibility and comfortable wearability at its price point.

Bremont Altitude Chronograph

Owners note faint marks on the case sides and back, with minor wear and creasing on the strap. Reviewers flag the "DANGER EJECTION SEAT" wordmark on the dial as a divisive design choice that disrupts the MB series' usual stark tone, though they praise the improved smoothness and click precision of the Roto Click rotating bezel. On balance, the Bremont Altitude Chronograph elicits mixed reactions, with design elements like the dial text being a point of contention for reviewers.
