Oris Divers Sixty‑Five Calibre 400vsMarathon Arctic OSAR 46mm Automatic

Owners and reviewers widely praise the Oris Divers Sixty-Five Calibre 400 for its refined finishing, comfortable bracelet, and the impressive Calibre 400 movement with its 5-day power reserve and 10-year warranty. The domed sapphire crystal and vintage-inspired design, including the tapered bracelet with rivets, are frequently highlighted.

However, some owners find the $3900 price point high, with one reporting a date wheel failure within a month and significant daily timekeeping issues after repair. The 10atm water resistance rating is also noted as a potential drawback by some. Overall, owners and reviewers rate the Oris Divers Sixty-Five Calibre 400 highly for its upgraded movement and compelling value.

Owners widely praise the Marathon Arctic OSAR 46mm Automatic for its overbuilt toughness and industrial, instrument-like aesthetic, with some preferring the Arctic dial for legibility. One owner notes the automatic movement may be unnecessary for rough use compared to a quartz option. Reviewers mention the MaraGlo luminous paint and a Sellita SW200-1 automatic movement. Some owners question its rising price and luxury positioning, with one reporting poor lume and movement performance. Overall, owners value the Marathon Arctic OSAR 46mm Automatic for its robust build and utilitarian design.
