OW Ocean Graph MkII

The Ollech & Wajs highly respected ‘Precision’ line has long been chosen by those who dare to venture deeper for its uncompromising dedication to professional-grade extreme water resistance. The original 1968 Ocean Graph became popular among both enthusiasts and professional divers for its robustness, 1000m water resistance, and specialised decompression bezel. The MkII honours this legacy while embracing advancements in watchmaking that enhance precision, durability, and versatility for the competitive diver.

The MkII is the product of a rare collaboration between Ollech & Wajs and Siri Østvold, Norwegian freediver and ocean advocate. Her experience beneath the waves informed key elements of the watch’s usability and aesthetics. From the multifunction ‘Dive, GMT, Tide tracking & top time’ bezel to the legibility of the hands and markers, every detail was tested against the real-world challenges faced by divers.

The Ocean Graph MkII, the latest evolution of one of the most iconic dive watches in history. Originally launched in 1968 as a specialised instrument for recreational and professional divers, the Ocean Graph defined a new standard in ocean exploration. The reimagined Ocean Graph MkII fuses contemporary engineering, modern functionality, and the insight of Norwegian freediver Siri Østvold, whose vision helped refine the design for the demands of competitive free divers.
