The Oris Aquis Pro 4000m was introduced in August 2023, not in 2026. Oris rates the 49.50 mm titanium dive watch to 400 bar, equivalent to 4,000 metres, and equips it with an automatic Calibre 400 movement and a lockable Rotation Safety System bezel. The depth rating is the manufacturer’s stated specification; the available sources do not establish an independent test report or certification standard.
How deep can the Oris Aquis Pro 4000m go?
Oris specifies a pressure rating of 400 bar, which it equates to a depth of 4,000 metres. The brand describes it as its most water-resistant watch. That is a manufacturer rating, not evidence that the watch is suitable for every professional dive or that it has an independently documented certification. Oris’s product page puts the claim this way: “As the name has it, we’ve now certified our professional diver’s watch to a pressure rating of 400 bar, equivalent to a depth of 4,000 metres.”
The figure is best understood as Oris’s stated pressure rating. The available product and launch materials do not identify a testing protocol or independent standards certification, so the rating should not be treated as a verified operational diving limit.

What does the Rotation Safety System do?
The Oris-patented Rotation Safety System is a bezel-locking mechanism developed with professional divers. It is intended to stop the bezel from being adjusted accidentally while timing a dive. A dive bezel is useful only if its elapsed-time indication stays where the wearer set it; RSS addresses that practical risk by adding a lock rather than relying on bezel friction alone. Oris describes the system in its Image Booklet 2024 and product booklet 2025.
How large is the watch, and what does that mean for fit?
The case diameter is 49.50 mm, making this a notably large watch. The titanium case may keep it lighter than a comparable steel case, but the size remains central to the design and can be challenging for smaller wrists or for anyone who prefers compact watches. Try it on if possible, especially with the rubber strap and extension clasp fitted as intended.

What is the Oris Aquis Pro 4000m price?
There is no single universal price in the cited listings. Oris’s regional product pages consulted in 2026 showed different currencies and amounts, while launch-era prices reflect a different date and market:
| Price | Source and context |
|---|---|
| USD 7,854 | Oris Chile regional product page, consulted in 2026 |
| CHF 5,800 | Oris Dominican Republic regional product page, consulted in 2026 |
| JPY 803,000 including tax | Japan launch price in Oris press-release text republished on 29 August 2023 |
| USD 6,200 | Original US retail price reported by Hodinkee at the 2023 launch |
These figures are not directly comparable current quotes: they cover different regions, currencies and dates. Check the official listing for your market or an authorized retailer for current local pricing and availability. The reference listed by Oris is 01 400 7777 7155-Set; a product page alone does not confirm current stock.

Oris announced the Aquis Pro 4000m in August 2023. WatchMediaOnline republished the press-release text dated 29 August 2023, and Hodinkee covered it at launch. It is therefore more accurate to describe the model as a 2023 introduction than as a new 2026 release.

What to weigh before choosing it
- Size: the 49.50 mm case makes fit a primary consideration, regardless of the depth rating.
- Use case: RSS is designed to help prevent accidental bezel movement when timing a dive; the rating alone does not establish suitability for every dive or operating condition.
- Ownership terms: Oris states a 120-hour reserve and ten-year recommended service interval. The ten-year warranty requires registration with MyOris; check the current warranty terms and registration conditions with Oris.
- Price: use a market-specific current listing rather than comparing regional prices or launch-era figures as though they were equivalent.
