The 'Ocean Graph', released by Ollech & Wajs in 1968, was an iconic model said to have established the strict standards for diver's watches. Welcoming renowned Norwegian female diver Siri Ostvord as a collaborator, the 'Ocean Graph Mk II' was jointly developed as a tribute to that famous timepiece.
