This year, Corum is launching a brand new version of its iconic watch with a unique set of complications that facilitate naval voyages through coastal regions. Thanks to the same movement which is now used in a novel package, new Admiral’s Cup AC-One 45 Tides is still the only mechanical timekeeper to include all the relevant information about the tides, despite the fact that this specific combo of indications originally appeared 21 years ago. Its automatic movement CO 277 offers information about the time, the strength and the height of the tides, the height of the currents, as well as about the current lunar cycle. The latest iteration of the iconic sea-faring watch is presented in a historic shade of blue which is used for both its dial and the strap, whereas it is encased in a titanium housing.
The main strength of Corum Admiral’s Cup AC-One 45 Tides is certainly its CO 277 caliber which first saw the light of day back in 1993. It was developed with the help of the famed creator of modules for mechanical movements, Dubois-Depraz, as well as with the input of relevant scientific institutions such as the National Hydrographic Service of the French Navy in Brest (also known by the acronym SHOM) and the Astronomic Observatory of Geneva. Corum and its associates spent three years of laborious work in order to create a movement that would provide all the needed information about the tides, which comes more than handy once you are sailing the coastal waters.
Everything You Need to Know about the Tides
Now, let us examine the supported functions a bit more thoroughly. The moon phase display, the indication which is closely tied to the tides since the relation of the moon’s and the earth’s positions causes it –– lies at the top of the watch’s face. When the moon is either full or new, the tides are at its pinnacle. On the contrary, when our satellite is in the first and the last quarters, the strength of the tides is at its low point. Apart from the classic indication for the moon stages, the 12 o’clock position likewise shows coefficient of the tides which is in the range of 95-120 at its amplitude, as well as between 20 and 45 when it is at its lowest point.
For the display of the time of the next two tides, the wearer should consult the sub-dial at the six o’clock place. The final associated display at the nine o’clock position informs the wearer whether the tide is in ebb or in flow. Caliber CO 277 also shows the current date which is displayed via an aperture.
As it has been said, the watch’s movement with 21 jewels which is 11 ½ lignes wide features self-winding. Once it is filled, its power reserve lasts for 42 hours. CO 277 operates at the rate of 4 Hz. When the finishing of the movement is concerned, it should be said that it possesses a skeletonized and round shaped rotor with the typical Corum decoration.
Titanium Case, Rubber Strap and a Brass Dial with Grenadier Fendu Finishing
Corum Admiral’s Cup AC-One 45 Tides is housed inside the brand’s typical dodecagonal shaped housing made of grade 5 titanium and with a layered structure. One of these layers placed around and beneath the fixed bezel and spreading all the way to the crown protector is treated with PVD coating in order to receive a blue color that matches the shade of the dial and the strap. The crystal is naturally constructed of sapphire with anti-reflective treatment. Despite the fact that the watch as the true representative of the Admiral’s Cup series has water resistance to 300 meters, it also includes a transparent sapphire section on the rear side of the housing. As for the dimensions, the diameter is 45 mm as it is clear from the watch’s name, whereas the thickness measures to 14.3 mm.
The Corum’s newcomer has a historical Corum blue colored dial made of brass. When compared to all of the past incarnations of the model with the tides info, this one possesses the most graphical indications on its sub-dials used for the tides information. Moreover, the face includes skeletonized hour and minute hands with luminous tips, hourly nautical pennants on the flange, as well as applied indices with rhodium coating and white SuperLuminova. The distinguished dial sports a Grenadier fendu finishing which makes it look textured and more striking. As for the bracelet of the watch with the reference number A277/02401 – 277.101.04/F373 AB12, it is made of a vulcanized rubber and it fastens with a titanium triple folding clasp with the brand’s logo.
