Crafted through DELMA's collaboration with IMOCA Ocean Masters, this Oceanmaster Chronograph represents the pinnacle of maritime timekeeping. It seamlessly integrates professional diving specifications with sophisticated sailing instrumentation—unidirectional bezel, tactical planner, and sail-point indicators work in concert to deliver precise race-start execution and real-time course monitoring. The high-contrast black dial with legible hands prioritises visibility of critical navigation data, whilst the chronograph mechanism captures elapsed time across multiple phases. Reinforced stainless steel construction incorporates crown guards and pairs with a robust rubber strap to withstand rigorous ocean environments. An IMOCA sailboat motif graces the case back, celebrating the watch's competitive lineage. Purpose-built for professionals who require uncompromising technical accuracy and authentic nautical heritage.
