An icon among sea-lovers now returns in a reworked design: the Admiral’s Cup AC One 45 Tides watch. 21 years after its launch, this model with its mechanical movement driving indications of the time and strength of the tides, the lunar cycle, as well as the strength of the currents and the height of the tides, remains a truly unique complication in the Fine Watchmaking world. Its exclusive nature forcefully reaffirms Corum’s longstanding, solid nautical anchorage.
From the dawn of time, the lives of seagoing professionals have been governed by the rhythms of the tides. In most part of the world, they follow a twice-daily lunar cycle, with the tide coming in on average every 12hrs 25 minutes, before receding again. Created in 1993, the CO 277 caliber beating at the heart of the Admiral’s Cup AC-One 45 Tides was specifically designed for these coastal regions.
The CO 277 caliber now provides its essential navigation-related indications on a striking red dial bearing subdials that are more graphically styled than ever. The Moon, which determines tidal movements, appears at 12 o’clock. When it is full or black (new moon), meaning when it is aligned the Earth and the Sun, 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.
