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.

Sternglas Naos Pro Automatik

The Sternglas Naos Pro Automatik is praised for its slim 9mm case and Bauhaus dial design, featuring clear hour markers and a framed date window. Owners note the upgraded Miyota 9015 movement with a 4Hz beat rate. Accuracy is reported as -10/+30 seconds per day, which is not ideal for precision enthusiasts. The five-link bracelet's lack of fitted end-links and the optional bracelet's chunkiness are flagged as areas lacking refinement. Overall, reviewers highlight the Sternglas Naos Pro Automatik's improved wearability and premium feel at its price point.

From video reviewers

The Bauhaus design is a strength. The value proposition is a weakness.
