Uncovering the Beauty of Mechanics

Corum has revealed the AC-One 45 Openwork Automatic, a robust timepiece that pushes the boundaries of watch design to another level. Introducing an exquisitely crafted skeletonised dial, the AC-One is fitted with a caliber CO 297 movement that was developed in-house by Corum specifically for this model.
Like 2014’s AC-One 45 Squelette, the architecture of the AC-One 45 Openwork Automatic juxtaposes this otherwise hefty timepiece with a touch of lightness and refinement. Unlike the squelette, however, Corum here utilises bolder and cleaner-cut lines to give the Openwork Automatic a more robust and athletic feel.
The AC-One Openwork Automatic also features redefined straps. Crafted with rubber on the surface and synthetic textile on the underside, the bi-material straps are designed to seamlessly integrate with the lugs. This minimises 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 aggression.
