The model features day, date, month, and moonphase indicators, all powered by an in-house caliber. This complex movement highlights Universal Genève’s engineering prowess at a time when such achievements were (and remain) rare for independent watchmakers. Despite its complexity, the watch achieves a clean and uncluttered dial design."
