Swiss-based ochs und junior manufactures only watches developed by Ludwig Oechslin, the legendary thinker behind some of the most awarded watches of the past 30 years. The watchmaker’s latest creation, the calendario cent’anni, “cca”, module contains a mere nine components that can accurately indicate the day, date, and year plus leap year for 100 years. Oechslin is known for radically reducing the number of mechanical parts in the brand’s watches because simpler mechanics are more reliable and easier to manufacture and service. The cca module is the pinnacle of Oechslin’s more than 30-year quest to simplify mechanical movements to the extreme.
While most watches rely on hands or discs to display the time, the 42mm ochs und junior calendario cent’anni is based on Oechslin’s ingenious simplification of telling time by a system of dots rotating around the dial. The 30+1 holes around the perimeter of the dial display the date, while the 10-minute markers serve as reference points and the small disc in the center of the dial indicates the month. When the outermost perforation points to 1-o’clock, this indicates January and when it points to 2-o’clock, it is February, and so on. The deceptively simple calendario cent’anni comes in three dial-plate colorways, including white, black, and brown.
