ZEROO M5 THE KIRCH MECHANICAL AUTOMATIC

ZEROO TIME was founded in December 2017 in Hachioji, on the western edge of Tokyo, around a deliberately immodest brief: rebuild the wristwatch from scratch. Under designer SYUU the house argues that case four ways — the C series reworking the moon-phase classic, the M series in thin tonneau and octagonal sports-luxe, the T series built to put a flying tourbillon within ordinary reach, and the DT double tourbillon that gave the line its ceiling. The tourbillons run on ZEROO’s own ZT and ZDT calibers, assembled in the company’s Tokyo atelier and framed by 316L steel, sapphire front and back, and dials skeletonised until the carriage is the whole view; the Modern and Classic pieces sit on Miyota automatics and quartz. Most references are limited runs, serial-engraved on the caseback.
