A revolutionary watch that doesn’t require calendar correction
until the end of February 2100.Perpetual Calendar

In 1998, a revolutionary watch was commercialized that eliminated the need for date correction over a long period of time. This was the Perpetual Calendar. With a high accuracy of ±20 seconds per year and a long battery life of 10 years (5 years for women’s watches), it will not require calendar correction until the end of February 2100, and boasts extremely high accuracy. The crown, which rarely needs to be operated, is embedded in the case, and the calendar is emphasized by the magnifying glass. In addition, the first piece of the bracelet has been lengthened to create a sense of unity from the case to the bracelet.
