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.

Zelos Thresher 44

Owners widely praise the Zelos Thresher 44, with one owner noting its finish has proven remarkably scratch-resistant. However, one owner found the finishing on their hammered grey variant not as well done as expected. The Zelos Thresher 44 with an agate dial sold out in 90 seconds, with one owner receiving theirs and noting the bracelet was fully wrapped. Overall, owners rate the Zelos Thresher 44 highly for its desirability and scratch-resistant finish.
