Uncovering the Beauty of Mechanics Corum pushes creative boundaries once again with the AC-One 45 Openwork Automatic and Automatic Tourbillon

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.

 

Taking mechanical beauty a step further: AC-One 45 Openwork Automatic Tourbillon

 

For aficionados who prefer something more complicated and gravity-defying, Corum has prepared the AC-ONE Openwork Tourbillon. At the six o’clock position lies a tourbillon, in addition to the above details present in the AC-One Openwork Automatic. This showcases the not only the beautiful heartbeat of the movement, but also Corum’s artistry and flare in technical watchmaking. The addition of a tourbillon also ensures higher accuracy in timekeeping under conditions at sea.

 

Both the AC-One Openwork Automatic and Openwork Tourbillon also feature redesigned straps. Crafted with rubber on the surface and synthetic textile on its underside, these bi-material straps are designed to seamlessly integrate with the lugs. This minimizes any possible gaps between the lugs, strap and wrist, which not only makes wearing the watch more comfortable, but also protects the lugs and straps from being damaged by external aggressions.
