Quick TakeSlicing through the waves of conventional watch design, the Admiral 45 Tourbillon Openworked isn't just a timepiece; it's a statement of maritime audacity wrapped in a cloak of mechanical artistry. Imagine the 72-hour power reserve as your personal wind, steadily filling your sails for three days straight, while the 3 Hz beat of the flying tourbillon is the rhythmic pulse of the ocean itself, a constant dance against gravity visible through the stunningly skeletonized dial. Those nautical pennant hour markers aren't just for show; they're a salute to the collection's seafaring heritage, a playful nod to a world of regattas and exploration. The robust 45mm titanium grade 5 case feels surprisingly light, yet it's as unyielding as a ship's hull against the pressures of 100 meters of water. Even the 3-minute counter hints at tactical timing, perhaps for the perfect sailing maneuver. This isn't just about telling time; it’s about strapping an openworked mechanical marvel to your wrist, a piece that feels both aggressively modern and deeply rooted in Corum's adventurous spirit, ready for whatever voyage lies ahead. The combination of vulcanized rubber and calfskin leather is the final touch – rugged, yet refined, like a seasoned captain.
DescriptionThe CO 298 automatic calibre serves as the mechanical heart of this horological instrument, engineered with a power reserve of 72 hours, ensuring sustained operation for three full days without requiring winding. Operating at a frequency of 3 Hz, equivalent to 21,600 vibrations per hour, the balance wheel within the flying tourbillon cage aims to deliver consistent timekeeping precision by counteracting gravitational errors. The movement's dimensions are noted as 12 1/2 lignes, a traditional watchmaking unit of measurement, and it incorporates 37 jewels to minimize friction at critical points, thereby enhancing durability and the efficiency of power transmission. Its functions extend beyond simple hour and minute display to include a visually prominent flying tourbillon, a power reserve indicator to monitor the remaining mainspring tension, and a specialized 3-minute counter, a feature with potential nautical applications or for timing short intervals. The openworked design of this calibre, a key characteristic of the timepiece, allows for an unobstructed view into the intricate workings and architecture of the movement, transforming its functional components into primary aesthetic elements. Production of this model is strictly limited to 38 units, underscoring its exclusivity.

Encasing the intricate CO 298 movement, the watch presents a formidable case structure measuring 45 mm in diameter and 14.30 mm in thickness. This substantial housing is fabricated from Titanium Grade 5, a material selected for its superior strength-to-weight ratio, exceptional corrosion resistance, and biocompatibility. The case architecture ensures water resistance up to 100 meters or 10 atmospheres, rendering the watch suitable for surface water activities. The dial, crafted from brass and finished in black, provides a contrasting background for the rhodium-plated, Dauphine-variant skeleton hands, which are treated with Black SuperLumiNova for enhanced legibility in low-light conditions. Further adhering to the Admiral collection's maritime DNA, the indexes are presented as rhodium-plated appliques configured as nautical flags. Attached to the case, with an interhorn width of 23 mm tapering to 20 mm, is a robust strap combining vulcanized rubber and calfskin leather in black, designed for both comfort and resilience. Security on the wrist is provided by a triple-blade folding clasp, also constructed from Titanium Grade 5, ensuring a cohesive material palette and secure fastening.
