The Oris Aquis Depth Gauge (ref. 01-733-7755-4154-Set-MB) is an automatic diver watch, with a 45.8mm stainless steel case, powered by the 733 movement and a 38 hours-hour power reserve. Water resistance is rated to 500m, under a sapphire crystal, with date complications. Manufacturer MSRP is $4,500.
The Oris Aquis Depth Gauge is widely praised for its unique mechanical depth gauge complication, which reviewers confirm is accurate and a clever application of Boyle's law. Owners and reviewers note its solid build, improved legibility with longer markers and wider hands, and a convenient quick-change strap system. The watch offers great value, with a tungsten bezel and 500-meter water resistance. However, the Oris Aquis Depth Gauge is criticized by multiple sources for its large case size, with dimensions ranging from 45.5mm to 48.5mm, and its significant weight, making it potentially unwieldy for smaller wrists. Its utility as a primary dive instrument is questioned due to the lack of a maximum depth indicator, and one owner expressed a dislike for the use of Sellita movements. Overall, owners and reviewers rate the Oris Aquis Depth Gauge highly for its innovative depth gauge mechanism and strong value proposition, despite its substantial size.
