Hello, this is Classical.
As always, this review is completely self-funded, with no connection to any brand. I believe in only reviewing watches that I have personally owned and worn for a significant period. Quick overviews or sponsored content that don’t reflect authentic, in-depth experience aren’t real reviews.

3. Purchase Motivation and Process
I have long been interested in the Oris Aquis line, and the Depth Gauge model stood out due to its functional uniqueness. Unlike conventional dive watches, this model features a mechanical system that allows for analog depth measurement.
Curious to test the depth gauge function in real diving conditions, I compared multiple models before making a decision. After trying it on in person, I found the wearability to be reasonable despite its size, and its practical features ultimately won me over.
4. Personal Evaluation
■ Stainless Steel Case
- With a 46mm case diameter, this watch is undeniably large. However, the compact lug design prevents it from feeling overly bulky on the wrist. The combination of a stainless steel case and a ceramic bezel insert provides a solid and durable feel.
- The unidirectional rotating bezel offers a distinct click with each turn. Its oversized teeth ensure easy operation, even when wearing diving gloves.
■ Depth Gauge Function
- The standout feature of this watch is its ability to measure depth using a fine channel within the case. As the diver descends, water enters the channel, utilizing internal pressure to indicate depth via the yellow scale on the dial’s outer ring.
- While it cannot match the pinpoint accuracy of electronic depth gauges, its execution in a fully mechanical timepiece is impressive. It adds real functionality to the watch and reinforces its identity as a professional dive instrument.
■ Movement
- The Oris 733 movement, based on the reliable Sellita SW 200-1, is a proven automatic caliber. It provides solid performance, though its 38-hour power reserve is relatively short compared to modern standards. However, for daily wear and diving purposes, this is not a major drawback.
- The screw-down crown enhances water resistance, and the crown guard is robustly designed for added protection. With a water resistance of 500m, this watch is built for serious underwater adventures.
5. Conclusion
The Oris Aquis Depth Gauge is more than just a dive watch; it is a tool designed for actual diving applications. Its unique analog depth measurement system sets it apart, making it an exceptional choice for enthusiasts who seek something beyond the standard diver.
However, the large 46mm size may not be suitable for everyone, and the power reserve is on the shorter side. Despite these considerations, the combination of functionality and originality makes this watch a compelling choice for dive watch enthusiasts.
For those who want a mechanical dive watch with a distinctive feature, the Oris Aquis Depth Gauge is a strong contender.
