The Oris Big Crown Pointer Date is an iconic mechanical pilot's watch known for its distinctive oversized crown and a central fourth hand that points to the date along the outer edge of the dial. The watch is available in several case sizes (36mm, 38mm, 40mm) and materials (stainless steel and bronze), with various movement options. Key Features and Design Oversized Crown: A signature feature designed for pilots to operate the watch easily while wearing gloves, contributing to its vintage aesthetic. Pointer Date Complication: Instead of a date window, a central hand with a distinctive tip (often red or arrow-shaped) indicates the date on a scale around the dial's periphery. This design is highly legible and helps maintain dial symmetry. Dial Design: The dial typically features large, luminescent Arabic numerals and "cathedral" or "pencil-shaped" hands for excellent legibility. Movement Options: The watch comes with either the reliable, Sellita-based Oris 754 automatic movement (offering around a 38-41 hour power reserve) or the in-house Oris Calibre 403 (which boasts a five-day power reserve, elevated anti-magnetism, small seconds at 6 o'clock, and a 10-year warranty). Crystal: Most modern versions feature a double-domed sapphire crystal with an anti-reflective coating on the inside for durability and clarity, mimicking the look of vintage acrylic crystals. Case Back: It typically features a screwed, see-through case back (usually mineral glass) that displays the movement's red oscillating weight. Water Resistance: Generally rated for 5 bar (50 meters) of water resistance.
