Abstract
In the quartz watch according to the invention all the time displaying hands (of the hours, the minutes and, possibly, the seconds) are kinematically permanently connected to each other, thus always displaying time in a very precise manner by their respective positions, whichever manipulations are made by the watch carrier. The addition to the conventional parts of the watch of a detector sensitive to the manually controlled displacements of the hands and of a counting device for finishing off these displacements and for memorizing the time impulses during the manual correction, ensures automatically setting the hands in the exact time indicating positions thus permitting the watch carrier who travels from one time zone into another one to make rapidly the necessary time alterations without prejudice of the previous precision of the time indication.
