The present wristwatch showcases the technical complexity that Roger Dubuis is best known for. The watch not only features a dual time function, it also houses an instantaneous perpetual calendar and moon phases complication. Fitted with the brand’s renowned instantaneous perpetual calendar mechanism, the watch provides a smooth and instant transition of the days without requiring any corrections. Once the hands pass midnight, the calendar instantly displays the day, date, month along with the leap year indicators through the apertures.

The present model was presented at the SIHH shortly before Richemont acquired the brand.
