Oris Aquis watches

The Oris Aquis is the brand's diving watch line. Oris launched it in 2011, and it remains the company's flagship. The first Aquis was a 300 m diver with a screw-down crown, a ratcheting unidirectional dive bezel, a domed sapphire crystal, a date at 6 o'clock and the Oris Caliber 733.

Two developments have shaped it since. In 2013 Oris patented the Aquis Depth Gauge, its first mechanical depth gauge: water enters a channel through a small hole at 12 o'clock, and the mark it reaches shows the depth. In 2020 came Calibre 400, an in-house automatic movement with a five-day (120-hour) power reserve, anti-magnetic to 2,250 gauss, with a recommended 10-year service interval. The Aquis Date Calibre 400 measures 41.5 mm, is water-resistant to 30 bar and has a ceramic top ring carrying the minutes scale.

The core of the range is the Aquis Date, in steel from 36 to 43.5 mm, with DLC-coated black versions and diamond-set dials and bezels among the smaller sizes. Calibre 400 models come at 41.5 and 43.5 mm, the 41.5 mm also in steel and yellow gold. Bigger cases carry more functions: the Big Day Date at 45.5 mm, the Small Seconds Date and the Chronograph at 45.5 and 46 mm, the Depth Gauge at 46 mm and the Depth Gauge Chronograph at 48 mm. Titanium appears on the Aquis Date 43.5, the Chronograph, the Titan Small Second Date and the 49.5 mm AquisPro Date Calibre 400 in DLC-coated titanium.

Oris also makes the Aquis in numbered editions: the Star Wars Stormtrooper of 1,300 pieces, the Blue Whale chronograph of 200, the Sun Wukong Artist Edition of 72 and the Carysfort Reef Gold, a solid yellow gold GMT with a 24-hour bezel, of 50. Many others are named after reefs, islands and lakes, such as Great Barrier Reef, Clipperton, Tubbataha and Lake Baikal.
