Corum Admiral is a watch with a celebrated legacy, loved for its distinctive dodecagonal case and appealing heft. So, when the house decided to iterate such an iconic style, it had to be nothing but extraordinary. And extraordinary is the Admiral's Cup Tides with such unique complications that its equal has not been found since.

This reference 277.931.06.0371-AN12 is the paradigm of nautical watchmaking, manifesting the house's maritime fondness most tastefully. It is powered by a highly-efficient automatic mechanical movement—calibre CO277. In addition to the conventional hours, minutes, seconds, and date functions, this calibre also wields several interesting navigation-related complications, displayed attractively on the dial. The solid black dial bears a sub-dial at 12, featuring a moon phase complication to determine the tidal movements. Additionally, this sub-dial specifies the strength of the tides. At six o'clock is a sub-register indicating the time of the two succeeding tides in the next 24 hours through a 24-hour scale. And finally, will the tides rise or ebb can be comprehended with the aid of the sub-counter at nine.

At Second Movement, the pre-owned division of Ethos Watches, we adhere to a rigorous verification process where expert watchmakers carefully inspect every watch to certify its authenticity, ensuring it is not counterfeit. We also go to the maximum extent possible to ensure that the timepiece is not a stolen property and that all duties are paid. However, in the absence of any central database, a 100% verification is unlikely for any pre-owned entity in India. Nevertheless, we can still provide a provenance guarantee for watches purchased from Ethos.
