Oris Aquis Pro 4000m Titanium Calibre 400 Professional Diver 49.5 mm [01 400 7777 7155-Set]

The Oris Aquis Pro 4000m Calibre 400 is not merely a dive watch—it is the ultimate expression of Oris engineering, innovation, and mechanical watchmaking expertise.

Created without compromise, the Aquis Pro 4000m represents the most capable mechanical dive watch ever produced by Oris. Designed to withstand depths of an astonishing 4,000 metres (400 bar), this extraordinary timepiece pushes beyond the requirements of professional diving and enters the realm of true engineering achievement.

Combining a lightweight titanium case, Oris's revolutionary Calibre 400 manufacture movement, a patented Rotation Safety System, and saturation-diving capability, the Aquis Pro 4000m stands among the most technically impressive luxury dive watches available today.

The Most Water-Resistant Mechanical Watch Ever Produced by Oris

With a depth rating of 4,000 metres, the Aquis Pro 4000m exceeds the requirements of virtually every diver on Earth.

To put that figure into perspective, 4,000 metres places this watch in the same elite category occupied by some of the most respected professional dive watches in the world. It is a remarkable demonstration of Oris's commitment to engineering excellence and showcases what is possible when performance is prioritized above all else.

Whether worn by a professional diver, collector, or enthusiast, the Aquis Pro 4000m delivers a level of capability that few mechanical watches can claim.

The Revolutionary Rotation Safety System

One of the defining features of the Aquis Pro 4000m is Oris's patented Rotation Safety System (RSS).

Unlike conventional dive watch bezels that rotate directly, the RSS requires the bezel to be lifted before adjustment can occur. Once released, the bezel locks securely into position.

This ingenious system dramatically reduces the risk of accidental bezel movement while diving and represents one of the most innovative safety features found on any professional dive watch currently in production.

It is a uniquely Oris solution to a problem that most manufacturers simply accept.

Powered by the Exceptional Oris Calibre 400

At the heart of the watch beats the award-winning Oris Calibre 400, one of the most important movements in modern independent Swiss watchmaking.

Developed entirely in-house, the Calibre 400 was engineered to address the most common concerns associated with mechanical watches.

Key advantages include:

• Five-day (120-hour) power reserve
• Elevated anti-magnetic resistance
• Enhanced reliability and durability
• 10-year recommended service intervals
• 10-year warranty upon registration with MyOris
• Outstanding daily accuracy

The result is a movement designed for real-world ownership while delivering the mechanical sophistication expected from a luxury Swiss timepiece.

Features include:

• Helium escape valve
• Saturation diving capability
• Titanium construction
