The calendario cent’anni, known as the cca, is ochs und junior’s newest addition to its array of “uncomplicated” complications. This 100-year calendar is based on Dr. Ludwig Oechslin’s ingenious simplification of telling time by a system of dots rotating around various parts of the dial. This timepiece gives a whole package of information from hour, minute, second, date and month up to the leap year. The grade 5 titanium case holds a Ulysse Nardin UN-320 Movement. The first ochs und junior to be built in series is available in 3 versions.
The calendario cent’anni is classic ochs und junior, teeming with individuality, understatement, and simplicity. It accurately displays:
- correct number of month date (28. 29. 30. or 31. days) for 100 years, without needing correction for the length of any month (including February in leap years), displayed via a traveling, rectangular dot on the date spiral.
- the month and leap years on a central rotating disk.
- The leap year and the three following years are displayed on a decentralized disc, rotating together with the position of the month-display.
- the central hour and minutes with the seconds rotating on a small disk at 6 o’clock.
While all this information appears to be effortlessly produced by a module consisting of a mere 9 individual components, this module is the pinnacle of Dr. Oechslin’s more than 30- year quest to simplify mechanical movements to the maximum. The time in hours, minutes and seconds is displayed by central hour and minute hands as well as an off-center seconds disk at 6 o’clock. The date is displayed via a square dot traveling clockwise around the signatory ochs und junior spiral. The rectangular dot will correctly display months with 28, 29, 30 or 31 days. Situated at the center of the dial is the date disk, which indicates each of the 12 months of the year by aligning the fine line of the annual disk with the outer 12-month perimeter of the date disk. The small annual disk rotates once every four years to indicate the leap year and the three following years, which is marked by a thicker line which, in a leap year, aligns with the fine line of the year disk. The calendario cent’anni comes in 3 different models: calendario cent’anni, “cca” III, calendario cent’anni, “cca” II and calendario cent’anni, “cca” I.
