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 Day Date

Owners and reviewers widely praise the Oris Big Crown ProPilot Big Day Date for its excellent legibility, clear dial with large numerals, and fine brushed finishing on the case and bracelet. The turbine-style bezel and instrument-inspired hands are frequently highlighted as unique design elements. However, several owners report that the lume fades quickly and the Sellita SW220-1 movement can be noisy, running approximately +10 seconds per day, though one owner reported +8 seconds per day and another noted accuracy of +2s/d on a different model. The bracelet clasp is described as having limited adjustment, and attaching or detaching the bracelet can be difficult due to tight tolerances, with some owners finding the 45mm case size too large for smaller wrists. Overall, owners and reviewers appreciate the Oris Big Crown ProPilot Big Day Date for its strong legibility and distinctive pilot watch design at its price point.

Lorier Zephyr

Owners widely praise the Lorier Zephyr for its stunning guilloche-style dial, refined and perfectly sized unique case shape, and comfortable wearability. The Miyota 9 series movement is noted by owners as being a little noisy, with a rotor whirring audible on quick hand movements. On balance, owners rate the Lorier Zephyr highly for its distinctive dial and case design at the price.

From video reviewers

The watch's vintage aesthetic and value for money are praised. The bracelet's refinement and perceived rattle are noted as a drawback.
