Designed for functional utility and modern aviation style, the Oris Big Crown ProPilot Big Date features a bold 41.00mm multi-piece stainless steel case inspired by turbine engine blades. Built around high legibility, its striking blue dial is anchored by an oversized date display and contrasting Arabic numerals, protected by a domed anti-reflective sapphire crystal. At the heart of the timepiece is the Oris Caliber 751 automatic movement, a Swiss-made caliber operating at 28,800 vph (4 Hz) that provides reliable timekeeping, instantaneous date correction, stop-seconds function, and a 38-hour power reserve. Completed with a matching stainless steel bracelet, 10 bar (100 meters) water resistance, and a see-through mineral glass case back, this watch seamlessly merges practical pilot aesthetics with everyday reliability.
