The annual calendar, launched in 1996, has been a great success for 20 years due to its clever construction. The annual calendar, which is adjusted only once a year, is located between the simple calendar and the perpetual calendar, and is one of the best sellers. The system automatically determines whether the end of the month is the 30th or the 31st, and adjusts the date only once at the end of February every year. The annual calendar displays the date, day of the week, and month name. Elegant forms, the finest materials and luxurious designs combine, with a variety of models with colorful dials and cases.
