The Oris Aquis Date Calibre 400 41.5 mm Ref. 01 400 7769 4125-07 4 22 75FC represents one of the most appreciated versions of the Oris Aquis collection, thanks to the combination of the iconic design of the Swiss diver and the prestigious in-house Oris Calibre 400, developed internally to offer high autonomy, precision, and magnetic resistance.

The 41.5 mm stainless steel case is multi-piece and features a unidirectional rotating bezel with a minute scale on a ceramic top ring, a solution that ensures scratch resistance and a high-level sporty aesthetic. The screw-in crown, the screwed case back with a sapphire crystal porthole, and water resistance up to 300 meters / 30 ATM make this model suitable for both daily use and diving activities.

The blue dial offers depth and brilliance, enhanced by applied indices and hands with luminescent material to ensure excellent legibility even in low-light conditions. Functions include hours, minutes, central seconds, and a date display with rapid correction.

The heart of the watch is the Oris Calibre 400, a manufacture automatic movement characterized by a 120-hour (5-day) power reserve, high resistance to magnetic fields, a frequency of 28,800 vibrations per hour (4 Hz), and dimensions of 30 mm (13¼’’).

The model is completed by a 22 mm blue rubber strap, a steel safety folding clasp, and a sapphire crystal domed on both sides with an anti-reflective coating on the inside. The Full Set package includes the original box, documentation, and international warranty.

The Oris Aquis Date Calibre 400 Blue 41.5 mm is an ideal choice for those looking for a premium Swiss Made diver, with an in-house movement, five-day autonomy, and one of the best warranties available in the segment thanks to the MyOris extension of up to 10 years.
