Abstract
PURPOSE: To obtain a global watch with hand indication by correcting the time range preset by a single switch operation.
CONSTITUTION: The time lag correcting switch 9 sets the flipflop circuit 11 as the corrective memory circuit by the output of the logic differentiation circuit when it is closed. This opens the AND gate 12 to allow the time lag correcting signal (for instance 32Hz) of the divider circuit 2 to be fed to the drive circuit 4 passing through the OR gate 3. The output of the AND gate is fed to the counter 13 as the time lag counter. When the number of counting reaches the preset value according to the unit of the time lag, the FF circuit 11 is reset. Thus, only pulses of the number preset is fed to the drive circuit 4 to perform time lag correction.
