Review of the Corum Admiral’s Cup AC-One 45 Tides: A historical timepiece with a unique complication

It is a well-known fact that the Admiral’s Cup is among the most popular and sought-after collections from Corum. Since its introduction in the market which was back in 1960, the Admiral’s Cup collection has steadily paved the way for Corum’s immense success in the world of fine watchmaking. Pegged as the core of the Corum universe, the Admiral’s Cup, with time, has evolved and enriched into a modern iconic timepiece. And the legendary Corum Admiral’s Cup AC-One 45 Tides is one such example.

The Corum Admiral’s Cup AC-One 45 Tides reaffirms the brand’s immense love for nautical engineering. The watch houses a unique complication that calculates the movement of tides, making it an exceptional tool for sea-going professionals in their naval endeavours. It is a handy safety measure to equip oneself with when venturing out into the sea or coastal areas.

Discover The Replica Watch:

Already an icon amongst sea-lovers, the Corum Admiral’s Cup AC-One 45 Tides is back after 21 years, with a brand new avatar. While redesigned and reworked in aesthetic, the spirit of the watch remains the same. At the heart of the watch, you will still find the same movement (CO 277 caliber) that was there when the model was first launched in 1993. Featuring an automatic mechanical movement that indicates the time, strength and height of the tides along with the strength of the currents, the watch is extremely unique. It is one of the rarest complications to find in the vast world of luxury watchmaking.

A Revolutionary Movement From 1993:

As mentioned before, while the Corum Admiral’s Cup AC-One 45 Tides is a new edition, the spirit and heart of the watch remain the same as they were 21 years ago. The watch is still powered by the elusive CO 277 caliber movement which was developed in collaboration with the Astronomic Observatory of Geneva and the SHOM (Hydrographic and Oceanographic Services of the French National Navy). A revolutionary movement that took more than three long years to create, the CO 277 caliber is the only movement in the world that features a tides indicator. It follows a twice-daily lunar cycle with a difference of about 12 hrs 25 mins approximately between each other.

The CO 277 caliber movement basically operates as a moon phase watch, wherein, the caliber calibrates the proximity of the moon with the earth and the sun which invariably controls the strength of the tide. Apart from its nautical indicators, the movement also incorporates the hour, minutes, seconds and date functions. Beating at the rate of 28,800 vph (vibrations per hour), the CO 277 caliber clocks in a power reserve of 42 hours.

The Dial: Displaying An Attractive Sporty Elegance With A High Legibility Ratio

Offering an attractive aesthetic appeal with technically innovative functions, the brass dial of the Corum Admiral’s Cup AC-One 45 Tides is clean, clear and flawlessly designed. The perfectly balanced subdials at 6, 9 and 12 o’clock along with the date display indicator at 3 o’clock, are set with a high legibility ratio which aids in reading the dial clearly and swiftly.

The subdial at 12 o’clock is made up of two parts. The inner part of the subdial houses a moonphase indicator while the outer part specifies the strength of the tide, also known as a coefficient. What is a coefficient? It is a tabular system that outlines the “size” or “magnitude” of the prospective tide. For example, if the moon is full or black, the strength/coefficient of the tide would range between 95-120, which is at its peak. This high range would drop down to a lower tidal strength/tide coefficient between 20-45 gradually during the first and the last moon quarters.
