Oris Big Crown Calibre 403 – Red Dial

Royal Jewelers is an authorized Oris dealer in the Boston area and offers the Oris Big Crown Calibre 403 with Oris’s 10-year warranty (with MyOris registration).

Royal Jewelers offers the Oris Big Crown Calibre 403, a modern evolution of a heritage pilot’s design. This 40mm stainless steel timepiece features a warm red dial with bold Arabic numerals, a small seconds subdial at 6 o’clock, and the brand’s signature central pointer date hand.

Housed within a multi-piece stainless steel case, the watch is powered by the in-house Oris Calibre 403, a chronometer-grade automatic movement with a 120-hour (5-day) power reserve. Functions include central hours and minutes, small seconds, instantaneous date, date corrector, stop-seconds, and a fine timing device. The movement is visible through the sapphire exhibition caseback.

A domed sapphire crystal with anti-reflective coating inside provides clarity and protection, while the stainless steel bracelet with folding clasp ensures a secure and comfortable fit. This model is water-resistant to 50 meters and includes Oris’s 10-year warranty when registered through MyOris.
