Excessively small, excessively on-trend, the J12 breathes new life into the mini watch with this XS version. The 19-mm case is a winning combination of steel, the collection's hallmark high-tech ceramic in black, and the magic of diamonds. In a halo of 32 precious stones with more diamonds on the ceramic bracelet, the black lacquered dial of the J12 XS shines sparkling light on the hours and minutes as they tick by, measured by a quartz movement. The guarantee of precision for this diminutive watch that is big on personality.
