Oris Big Crown ProPilot Big Day DatevsMarathon OSAR-D (Original SAR with Date) Automatic 41mm

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.

The Marathon OSAR-D (Original SAR with Date) Automatic 41mm is noted for its highly legible white dial with applied hour markers and a functional date magnifier, emphasizing its tool-watch purpose. Its Swiss-made Sellita SW200-1 movement is considered reliable and serviceable. One reviewer found the bracelet lacked refinement and preferred the rubber strap option. Overall, owners and reviewers appreciate the Marathon OSAR-D (Original SAR with Date) Automatic 41mm for its excellent legibility and robust movement.
