Corum Admiral AC-One 45 Openworked Automatic: Malaysia Price And ReviewWritten by Leong Wong
Corum dares to bare.
The openworked dial is an aesthetic that goes one step beyond the skeleton watch, in that it reveals the entire mechanics by doing away with the dial altogether. This allows a glimpse into a world rarely seen beyond the walls of a Manufacture. Even a casual observer would be hard-pressed not to admit how entertaining it can be to witness what makes a watch tick quite so literally.
Once the domain of classic and dress pieces, the openworked aesthetic has made a successful, if perhaps unexpected, transition to the sports watch arena of late. In response, the watchmakers at Corum have flexed their creative muscles by not only making amazing movements, but also finishing them beautifully for those lucky enough to enjoy the hypnotic moving parts, especially the escapement.
This year, Corum pushes the boundaries once more for the Admiral range with another openworked model that has a totally new execution. The bolder and cleaner-cut lines of the Admiral AC-One 45 Openworked Automatic builds on its seafaring DNA with a styling that’s best described as athletic and robust. This clever architecture also gives the otherwise hefty timepiece a touch of lightness and refinement. Of course, it goes without saying that getting the chance to view in action the Calibre CO 297—a new movement that was developed by Corum in-house specifically for this model—is certainly a bonus.
The AC-One Openworked 45 Automatic has 12 pennants demarking the hours. They also act as anchors for the skeletal bridges that hold in place the spring barrel at 12 o’clock, the power reserve indicator at three o’clock, the balance spring at six o’clock and the three-minute counter at nine o’clock. Since this makes the dial pretty busy, the movement has been blackened to ensure legibility; otherwise, it would be too difficult to read the time at one glance.
The now-iconic dodecagonal case comes in two variants. The first, crafted in grade 5 titanium, lends an edgy vibe, while the second pairs rose gold with black PVD-coated titanium for a sportier feel. Meanwhile, the back of the movement is visible through the screwed-in open back bronze cover with an anti-reflective sapphire crystal.
Finally, the AC-One Openworked 45 Automatic features a revamped strap crafted with rubber on the surface and synthetic textile on its underside. All effort has been made to minimise the gap between the lugs, strap and wrist to ensure both comfort for the wearer and protection for the lugs and straps from external aggressions.
