Self-Winding Cricket Calibre V-21

The iconic calibre from the Manufacture

TIME FOR AN AUTOMATIC ALARM

Vulcain watches have been the privileged partners of the greatest American presidents Harry S. Truman to Barack Obama.. While each of them was accustomed to awakening to the sound of the famous Cricket alarm movement, all had to wind their watch manually.

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.

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. It beats at a cadence of 18,000 vibrations per hour and is endowed with a 42-hour power reserve. 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.
This results in more regular amplitude and thus enhanced precision and improved regularity of rate on the wrist.
