The SB10 Black Sapphire replaces the traditional dial with a smoked sapphire cabochon that offers a veiled glimpse into the watch's mechanical architecture — the jumping hour disc, the patented module, and Sartory-Billard's custom typography all visible beneath a dark, translucent surface. Hours jump cleanly through a generous aperture at six o'clock, while a Super-LumiNova BGW9 ring on a sapphire minute disc orbits the cabochon once per hour, delivering a striking turquoise halo after dark. Built on La Joux-Perret's G100 calibre with a 55-hour power reserve and housed in a 39.5 mm steel case, this is Sartory-Billard's tenth-anniversary statement distilled into something you can actually wear every day.
