Oris Divers Sixty-Five 12H Calibre 400 – Swiss Automatic Dive Watch This Oris Divers Sixty-Five 12H Calibre 400 is a modern interpretation of a historic Oris dive watch, combining timeless retro design with one of the most advanced in-house movements produced by the brand. The Divers Sixty-Five collection is celebrated for its relaxed, vintage-inspired aesthetic, and in this version it is elevated by the introduction of the Calibre 400, Oris’ game-changing five-day automatic movement. The watch is housed in a 40 mm multi-piece stainless steel case, a perfectly balanced size that offers excellent comfort and everyday wearability. The distinctive 12-hour bezel allows for tracking a second time zone, making this model particularly appealing to frequent travelers and collectors seeking both style and functionality. A domed sapphire crystal with anti-reflective coating on the inside enhances legibility while preserving the vintage character of the design. At its heart beats the Oris Calibre 400, an in-house Swiss automatic movement developed to set a new benchmark for reliability and long-term ownership. It offers an impressive 120-hour (five-day) power reserve, high resistance to magnetism, a fine timing device, stop-seconds function, and extended service intervals. This movement represents Oris’ commitment to independent watchmaking and mechanical innovation. The black dial features clean, highly legible markers and hands, with a discreet date window and luminous details for low-light visibility. The watch is fitted with a stainless steel three-link bracelet that complements the case design and ensures durability and comfort.
