Corum Admiral’s Cup AC-One 45 Tides

21 years after its launch, the Admiral’s Cup AC-One 45 Tides watch remains a powerful model in the fine watchmaking world. In most parts of the world, seagoing professionals are governed by the tides. They follow a twice-daily lunar cycle with the tide coming in every 12 hours and 25 minutes. Created in 1993, the CO 277 caliber beating at the heart of the Admiral’s Cup AC-One Tides was specifically designed for coastal regions.

No less than three years of development, conducted in collaboration with the Astronomic Observatory of Geneva and the SHOM (Hydrographic and Oceanographic Services of the French National Navy) based in Brest, were required to create this highly exclusive tides movement.

The CO 277 caliber now provides its essential navigation-related indications on an ocean blue dial bearing sundials that are more graphically styled than ever. The Moon appears at 12 o’clock. When it is full or black, the amplitude or strength of the tides, indicated by a dedicated hand on the dial is at its peak, with a coefficient of between 95 and 120, dipping to between 20 and 45 during the first and last moon quarters.

The legible sundials are arranged on a main dial adorned with the watchmaker’s famous split pomegranate motif. The bright blue is visually striking and is a great piece for the upcoming summer months.
