An annual calendar is mid-way between a perpetual calendar and a simple calendar: it recognises days of 30 and 31 months, but it must be manually corrected once a year at the end of February. This complication, which has enjoyed phenomenal success, is a standout feature of Ulysse Nardin watches. Whereas traditional mechanisms comprise around 30 components, the Manufacture from Le Locle has succeeded in developing one containing only around a dozen. This quest for simplicity – also guaranteeing exceptional reliability – has become an authentic brand philosophy. The time and calendar indications of this new Marine Chronograph Annual Calendar may be adjusted either forwards or backwards without any risk of inadvertently damaging the in-house movement. A mechanical gem that is a worthy descendant of marine chronometers.
