For the 2004 Opus 4 the typical Harry Winston round case made a reappearance – but now fully revearsable, enabling to show either one of two dials at the owners discretion. Made in collaboration with Christophe Claret, it featured chiming functions (minute repeater) and a tourbillon visible from the ‘technical’ side, while the other side revealed a more whimsical moonphase and date. Both dials showed the time. The movement contained a total of 423 parts.
