What people say

Owners + reviewers, side by side

Synthesized for each watch independently from owner discussions, enthusiast forums, written reviews, and video reviewers.

Oris Aquis Pro 4000m

The Oris Aquis Pro 4000m is widely acknowledged as a substantial dive tool, with reviewers and owners alike noting its impressive 49.5mm diameter and 23.4mm to 25mm thickness. Despite its size, the titanium case and comfortable rubber strap contribute to surprisingly good wearability for some, though others find its dimensions impractical for daily wear. The patented Rotation Safety System for the bezel is praised for its intelligence and functionality, while the in-house Calibre 400 movement offers a 120-hour power reserve and a 10-year warranty. One owner notes that the clasp's quick-adjust pushers can be unintentionally activated during watch removal. Overall, owners and reviewers regard the Oris Aquis Pro 4000m as a stunning, albeit chunky, tool watch whose impressive specifications are its primary draw.

Christopher Ward C65 Aquitaine Bronze COSC

Owners widely praise the Christopher Ward C65 Aquitaine Bronze COSC for its comfortable wearability, durable case and bezel, and smooth winding action, with one owner finding its case superior to a Tudor's. However, accuracy is a significant concern, with one owner reporting +17 seconds per day. The rubber strap is also noted as lacking refinement, and some suggest design tweaks for greater brand uniqueness. Overall, owners rate the Christopher Ward C65 Aquitaine Bronze COSC highly for its wearability and case finishing, despite accuracy concerns with the Sellita SW330-2 movement.
