Corum pushes creative boundaries once again with the AC-One 45 Openwork Automatic and Automatic Tourbillon April 23, 2019 Men Accessories 188 In 2013, the Admiral collection welcomed a new line to the family- the Admiral AC-One. Keeping in mind the key design codes of the Admiral Collection, the lines of the iconic dodecagonal-shaped case was reworked to become more rounded, and angles less prominent. Taking into consideration the size and weight of the 45mm diameter-case of the AC-One 45, titanium became the material of choice for this contemporary reinterpretation. Designed as a robust timepiece to complement luxury offshore boating, the Admiral AC-One 45 is even sportier, bolder and pushes the boundaries of creativity a step further. This year, Corum presents the AC-One 45 Openwork Automatic, which introduces an exquisitely crafted skeletonized dial. The movement fitted within the AC-One Openwork Automatic is the caliber CO 297, a new movement that was developed by Corum in-house specifically for this model. The bridges visible on the dial side were specially designed to be in harmony with the dodecagonal-shaped case, as well as the silhouettes of the nautical pennants. A sub-dial displaying small seconds is at the 9 o’clock position, while the power reserve indicator sits at 3 o’clock. Like the AC-One 45 Squelette that was released in 2014, the ingenious architecture of the AC-One 45 Openwork Automatic juxtaposes this otherwise hefty timepiece with a touch of lightness and refinement. Unlike the Squelette which features a completely skeletonized double-date disks, Corum makes use of bolder and cleaner-cut lines to give a more robust and athletic feel to the Openwork Automatic. The AC-One 45 Openwork Automatic is presented in two variants. The first, with a case crafted in grade 5 Titanium to add lightness of the overall design, and at the same time evoke a futuristic vibe. The second variation pairs contrasting rose gold with black PVD-coated titanium as the case material, giving the watch a bolder and sportier feel. The back of the movement is visible through the screwed-in open back bronze cover with anti-reflective sapphire crystal. Both timepieces offer water resistance up to 100 meters, while the movement has a power reserve of 42 hours.
