Experience the new benchmark of modern Swiss dive watch engineering with the Oris Aquis Date Calibre 400 43.5mm. Unveiled as the flagship ambassador for Oris’s revolutionary in-house movement development, this high-performance timepiece combines contemporary luxury sports styling with industrial Swiss horology. Engineered for serious oceanic exploration and refined boardroom presence, the Calibre 400 Aquis stands among the most capable modern divers in its class.

Sunburst Blue Dial & Ceramic Unidirectional Bezel

The focal point of this timepiece is its radiant ocean-blue sunburst dial, which shifts dynamically from vivid azure to deep navy in varying light conditions. Engineered with symmetrical balance, the date window is cleanly positioned at 6 o’clock, complemented by bold applied indices and alpha hands generously treated with Super-LumiNova for effortless underwater legibility. Framing the dial is a unidirectional rotating 120-click dive bezel equipped with a scratch-resistant deep blue ceramic insert, engineered with a legible minute scale to measure elapsed dive times accurately.

Solid 300-Meter Water-Resistant Steel Case

Constructed from premium multi-piece 316L stainless steel, the 43.5mm case delivers an assertive, modern wrist presence while remaining exceptionally wearable thanks to its short, ergonomic downturned lugs. The case is equipped with integrated crown guards, a screw-down security crown, and a domed sapphire crystal with internal anti-reflective coating, ensuring an impressive 300-meter (30 bar / 1,000 ft) water resistance rating. Fitted to its original solid stainless steel multi-link bracelet with a safety folding clasp and diver extension, this Swiss 300m ceramic bezel diver transitions effortlessly from deep-sea adventures to executive tailoring.

Groundbreaking In-House Oris Calibre 400 Movement

Visible through the oversized sapphire exhibition caseback is the star of the watch: the Oris in house automatic dive watch movement—Calibre 400. Engineered over five years from the ground up, this automatic caliber delivers an astonishing 5-day (120-hour) power reserve driven by twin mainspring barrels. Incorporating over 30 non-ferrous components and a silicon escapement wheel, it provides superior resistance to everyday magnetic fields from computers and smartphones, operating at a high-beat 28,800 vph for dependable precision.
