Complication with Islamic-Gregorian dual calendar available
The Islamic calendar began in 622 AD and is still used in most Islamic countries. To integrate the Islamic 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 shaped watchcase measuring 42mm in diameters indicating hours and minutes with two large hands in the center of the dial.
