The Oris Divers Sixty-Five Chronograph 01 771 7791 4051-07 8 20 18 is a high-performance Swiss-made automatic watch that masterfully revives the spirit of Oris’s first diver’s models from 1965. It features a versatile 40 mm multi-piece stainless steel case paired with a matching steel bezel that features a relief-engraved scale for tracking elapsed time. The clean, silver-white dial is arranged in a classic "bi-compax" layout with two sub-dials, providing a balanced and vintage-inspired aesthetic. Underneath the dial lies the Oris Calibre 771 automatic movement, which delivers precise chronograph functionality and a 48-hour power reserve. Enhanced visibility is ensured by the applied indices and hands filled with Super-LumiNova, all protected by a highly domed sapphire crystal with an anti-reflective coating. This model is water resistant to 100 m (10 bar) and features a screw-down crown to maintain its integrity during aquatic adventures. The watch is completed by a tapered multi-piece stainless steel bracelet that offers a comfortable and secure fit on the wrist. Combining mid-century sports watch charm with modern mechanical reliability, this chronograph is an ideal choice for enthusiasts who appreciate both history and utility.
