The new self-winding Cricket Calibre V-21 is also equipped with Vulcain's patented Exactomatic system which equalises the friction on the balance-staff in all positions by modifying the endstones of the incabloc shock-absorbers. It beats at a cadence of 18,000 vibrations per hour and is endowed with a 42-hour power reserve. Like its predecessor, the self-winding Cricket Calibre V-21 is a 12-lignes (12''') movement equipped with twin barrels: one to deliver the energy required for the hour, minute and seconds functions and the other to control the alarm function and its 20-second ring. The self-winding Cricket V-21 alarm calibre was entirely developed by the Vulcain constructors and masterwatchmakers on the basis of an even more accurate and reliable version of the legendary Cricket Calibre V-10, and thus representing the sum of more than 60 years of evolution and improvements, the automatic alarm movement shares a definite family likeness with its forebear.
