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.

Fortis Marinemaster M-44

The Fortis Marinemaster M-44 is praised for its excellent build quality and wearability, featuring a highly legible dial and a COSC-certified Kenissi-based movement that ran at 0 seconds per day. Owners appreciate its 70-hour power reserve and the inclusion of multiple straps and a deployant buckle, noting its gorgeous appearance and great wrist presence. A minor point raised is the 21mm lug width, with a wish for it to be 22mm. The Fortis Marinemaster M-44 is priced at $4,150. Overall, owners and reviewers rate the Fortis Marinemaster M-44 highly for its robust specifications and comfortable wearability at its price point.
