Oris Aquis Date Calibre 400vsOris Divers Sixty‑Five

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 widely praise the Oris Divers Sixty-Five for its vintage charm, wearable 40mm size, and legible dial, with many noting it wears thinner than its specifications suggest and appreciating its elegant, anachronistic design. The dramatically domed sapphire crystal is a highlight, and some find the 12-hour bezel a fun addition. However, some owners feel its lume leaves something to be desired, and one noted the crown can be bothersome to manipulate. The Sellita SW 200-1 movement offers a 38-hour power reserve, while the Calibre 400 movement offers a 10-year warranty. On balance, owners and reviewers rate the Oris Divers Sixty-Five highly for its vintage aesthetic and comfortable wearability.
