The calendario cent’anni is ochs und junior’s newest addition to its already impressive array of remarkably “uncomplicated” complications. It 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 is classic ochs und junior, teeming with individuality, understatement and simplicity. It accurately displays:
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 calendario cent’anni is not customizable, but comes in 3 different models.
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.
