The Oris Aquis has long stood out as a thoroughly modern dive watch packed with handsome versatility and a style distinct from other divers on the market. After many years and refinements, the newest model looks sleek as ever, but the most exciting element is what's inside. Oris has announced a new in-house automatic movement with some impressive qualities, and the competitively priced Aquis Date is the first to feature it.
The new Oris Calibre 400 was designed from the ground up, rather than based on an existing movement, and it offers automatic winding with simple three-hand time telling and a date display. It's made to be highly antimagnetic with numerous components made of non-ferrous materials, including silicon for the escape wheel and anchor. It further offers a whopping 120 hours (five days) of power reserve. The brand further emphasizes its quality by offering a 10-year warranty on the movement and promises an accuracy of -3/+5 seconds per day, which places it within the standards of a chronometer certification.
Like other Aquis watches, the movement is visible through a display case back while retaining a dive-ready 300 meters of water resistance. The sourced Sellita-based movements found in other Oris watches have the brand's signature red rotor, but the new movements have their own rotor and an expansive display window. It might not be decorated to haute horlogerie standards, but this is an impressive movement and cool to observe.
This first implementation of the movement looks refined with its gradient blue dial and ceramic bezel but might not be immediately distinguishable as special among other Aquis Date watches. It's the same boldly sized 43.5mm steel case that feels appropriate for a tool watch, and short lugs help keep it more wearable. Though the bracelet/strap is integrated into the case design and requires a proprietary connection, it does have a quick-change feature for easy swapping.
