Part of Oris’s popular Big Crown collection, the ProPilot has a traditional aviator look, built to the Swiss company’s exacting standards. As with the other timepieces in the collection, the Big Crown ProPilot has a large knurled crown and a prominent coin-edge bezel. The dial, which comes in gray or black, is appointed with large Arabic numerals in true pilot style. At 3 o’clock, you’ll find a day-date window, which is supported by Oris’s Calibre 752 automatic movement. Flip the stainless steel case over and you can see the movement in action. Fitted with a sapphire crystal, the watch is water resistant to 100 meters.
