Sky Dweller's Saros Calendar is based on an astronomical phenomenon called the Saros cycle, which lasts approximately 18 years and 11 days and is used to predict eclipses of the Sun and Moon.
There are many different types of calendar complications in mechanical watchmaking. The most representative ones are the day date, which displays the month/day, and the perpetual calendar, which accurately displays the calendar including a leap year function. Occupying somewhere in the middle is the annual calendar. It doesn't recognize leap years, but can automatically correct for months that contain 30 and 31 days. The annual calendar allows calculations for all months except February, so if you set the date to March 1st, calculations up to February 28th of the following year are automatically performed.
The Saros Calendar of the Sky-Dweller can also be viewed in the same form as this annual calendar. However, the concept of indicating the month using the red mark above the index is a unique system that cannot be found anywhere else, so it can be considered a new name.
