Oris Aquis Date Calibre 400vsBremont Altitude Chronograph

The Oris Aquis Date Calibre 400 is widely lauded for its exclusive in-house movement, offering a five-day power reserve, 10-year warranty, and 10-year service interval. Reviewers and owners praise its impressive accuracy, with figures ranging from under a second per day to seven seconds fast per day. The watch features a refined case with slimmer lugs and an updated dial for improved ergonomics, a patented quick-change system for straps, and a smooth, precise bezel action. Some find the dial can be shiny with glare from the domed crystal. Overall, owners and reviewers rate the Oris Aquis Date Calibre 400 highly for its significant advancements in mechanical watchmaking and value proposition.

Owners note faint marks on the case sides and back, with minor wear and creasing on the strap. Reviewers flag the "DANGER EJECTION SEAT" wordmark on the dial as a divisive design choice that disrupts the MB series' usual stark tone, though they praise the improved smoothness and click precision of the Roto Click rotating bezel. On balance, the Bremont Altitude Chronograph elicits mixed reactions, with design elements like the dial text being a point of contention for reviewers.
