The lslamic calendar which began in 622 AD and is still used in most Islamic countries. To integrate the lslamic calendar together with the conventional Gregorian calendar on a mechanical wristwatch is a unique feature worldwide. The Etoile Dual-calendar wristwatch is housed in an octangular watchcase measuring 42 mm indicating hours and minutes by two large hands in the center of the dial.
The date of the Gregorian calendar is indicated by a retrograde-hand starting from the left at 10 O’clock and ending at the right at 2 O’clock with the 31st day of the month. The date of the 30 days of the lslamic calendar are indicated at 6 O’clock with Arabic numerals.
At 4 O’clock the retrograde hand starts indicating the first month of the Hijri calendar and ends at the left side of the dial at 8 O’clock with the last month.
