Oris Divers Sixty‑Five 12h Calibre 400vsMarathon Arctic OSAR 46mm Automatic

Owners widely praise the Oris Divers Sixty-Five 12h Calibre 400 for its refined finishing, comfortable tapered bracelet, and the Calibre 400 movement's 5-day power reserve, 10-year warranty, and 10-year service interval. The 12-hour bezel is noted as useful for travel, and the domed sapphire crystal creates appealing light play. Accuracy is reported as precise, with one owner seeing +1.6 seconds per day. However, some find the watch bland and overpriced at $3900, questioning its dive watch credentials with 100m water resistance. One owner reported issues with the date wheel and accuracy after a month, and the date window's black fill is noted as not perfectly matching the matte dial. Overall, owners rate the Oris Divers Sixty-Five 12h Calibre 400 highly for its movement upgrades and elegant, wearable design.

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.
