The Oris Aquis Date Calibre 400 41.5 mm Ref. 01 400 7769 4127-07 4 22 77FC represents one of the most significant evolutions in the Oris Aquis collection, thanks to the integration of the prestigious Oris manufacture Calibre 400, an automatic movement developed in-house by the Swiss Maison to offer greater autonomy, precision, and magnetic resistance.

The 41.5 mm stainless steel case features a multi-piece construction with a minute scale on the ceramic top ring, combining robustness with high-level finishing. The screw-in crown, the screw-down case back with a sapphire crystal porthole, and water resistance up to 300 meters / 30 ATM confirm its professional vocation as a diver's watch.

The green dial gives depth and character to the timepiece, with a sporty yet refined shade that enhances the ceramic bezel and luminescent elements. Functions include hours, minutes, central seconds, date indication with quick-set, and stop-seconds.

The heart of the watch is the Oris Calibre 400, an automatic manufacture movement with advanced anti-magnetic technology, a 120-hour (5-day) power reserve, a frequency of 28,800 vibrations/hour (4 Hz), and dimensions of 30 mm (13¼’’). The movement uses high-efficiency components designed by Oris to ensure reliability and long service intervals.

The model is completed by a 22 mm black rubber strap with a steel security clasp, interchangeable with other compatible Oris straps. The crystal is sapphire, domed on both sides with an anti-reflective coating inside, while the transparent case back allows one to admire the automatic movement.

The Oris Aquis Date Calibre 400 Green 41.5 mm is an ideal choice for those seeking a high-end Swiss Made diver, with an in-house movement, 5 days of autonomy, premium materials, and a warranty extendable up to 10 years via MyOris registration.
