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.

Phoibos Leviathan

Owners widely praise the Phoibos Leviathan for its excellent value, superb case finishing, and generous lume. The watch is described as visually striking, legible, and well-made, with a unique case design, sapphire crystal, and a comfortable FKM strap or excellent bracelet with a milled clasp and quick adjustments. Some owners note the bezel's staggered jimping can cause fingers to slip, and the beveled crystal can distort the view of indices. Accuracy varies, with one owner reporting losing 5-10 seconds per day without a winder, while others state it keeps accurate time out of the box. The watch is frequently described as heavy and thick, with some owners finding it too large for wrists smaller than 7.5 inches, although newer models feature an improved clasp for better comfort and functionality. Overall, owners rate the Phoibos Leviathan highly for its striking design and impressive finishing at an accessible price point.
