Oris Big Crown ProPilot Big Day DatevsYema Flygraf Navigator

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.

Owners widely praise the Yema Flygraf Navigator's value and attractive design. However, community members express concerns regarding quality control and customer service, with one owner advising against purchase due to these issues. The in-house MBP1000 movement is noted as a mix of components, and one owner doubts its long-term reliability. On balance, owners find the Yema Flygraf Navigator a nice-looking watch with good value, but significant concerns exist around quality control and customer service.
