Corum Admiral AC-ONE 45 Chronograph

The “60” hour marker at 12 o’clock has been replaced by the Corum key and brand logo, which have been slightly enlarged to give better brand visibility. Another benefit from this minor design modification is the introduction of more breathing space on the dial—the watch face of the previous incarnation felt busier and with this small change, the Admiral AC-One 45 Chronograph looks sleeker and more contemporary.




For the chronograph display, Corum stuck to the same tri-compax arrangement but what has changed is the dial design. The watch face comes with a “Grenadier fendu” motif, which is a unique pattern worked on by a team of experienced designers back at the Corum manufacture in La-Chaux-du-fonds. This also means that the dial is only unique to the brand.
