For the ultimate ten pieces of the initial fifty-piece series of its first watch, the Carillon Tourbillon Minute Repeater, launched just a year ago, the young independent Maison Biver wished to pay a particular tribute to the dial maker’s artistry – by proposing two original dial options. The first dial, crafted from black obsidian, creates a striking contrast with the warm preciousness of the rose gold case. The second, in mother-of-pearl, enhances the elegant simplicity of the titanium version. In both designs, the case dimensions remain the same, with a reasonable diameter of 42 mm and a restrained thickness of 13.70 mm. The movement is the automatic JCB-001 caliber with micro-rotor winding; it beats at 21,600 vibrations per hour (3Hz) and offers a 72-hour power reserve.
