Aquis Depth Gauge

The Oris Aquis Depth Gauge is a standout among modern dive watches, uniquely engineered with a patented depth gauge system that lets water enter a channel in the sapphire crystal, allowing real-time depth readings right on the dial. This innovation sets it apart in the Oris lineup, appealing to divers and collectors drawn to functional ingenuity and bold, purpose-driven design. Its 46mm stainless steel case is substantial on the wrist, hinting at the serious underwater intent behind this model.

Reference numbers to know include the original 01 733 7675 4154 and later updates with minor dial and movement tweaks. Pricing varies with condition, completeness (box, papers, original strap), and whether you’re looking at earlier iterations or the more recent versions with the upgraded Oris Calibre 733 (based on the Sellita SW200-1). The depth gauge feature is unique at this price point, but note that servicing the crystal’s channel system is more specialized than with standard divers.

Water resistance is rated to 500 meters, making it a serious tool for diving, not just desk diving. The Aquis Depth Gauge’s large case means it wears best on medium to large wrists, and the integrated rubber and bracelet options both have a comfortable, secure fit. When evaluating pre-owned examples, check the condition of the depth gauge channel and crystal for any signs of improper use or damage, as these can affect both performance and value.
