The design blends classic and modern elements, with options for numerals or hour markers and hollowed counters. The caseback showcases a special medallion featuring the historic Montbrillant building. The reference AB013067.C894 boasts a stainless steel case and a sleek Aurora Blue dial with applied stick markers.
