Universal Genève Tri-Compax chronograph with black dial, moonphase display and vintage tachymeter bezel

TRI-COMPAX

Launched in 1944, the Tri-Compax was the first full-calendar chronograph to be industrialized, making it one of the most complex watches of its time. This model features day, date, month and moon phase indicators, all powered by an in-house caliber. This complex movement showcases Universal Genève's technical prowess at a time when such achievements were (and remain) rare for independent watchmakers. Despite its complexity, the watch features a clean, sober dial, all in a case 36 mm in diameter and 12.5 mm thick. In the 1960s, the Tri-Compax was reissued as a sports watch, acquiring iconic status when it was frequently worn by legendary musician Eric Clapton.

Design Simplicity

By moving the tachometer to the non-rotating outer bezel, the otherwise complex dial achieves a distinctive purity.
