Unlike other timepieces made with raw bronze, that will age or even deteriorate with time, Corum has pushed the envelope to the limit by developing a fully pre-patinated bronze case. Exclusive to the brand, this treatment gives the piece a more pronounced maritime look, and above all results in a more finely-crafted aspect than raw bronze designs. Each Admiral AC-One 45 Chronograph Bronze is unique in its own way, too: no two patinas give the alloy exactly the same colouration.
