ABNORMAL DISPLAY OR IMPROPER FUNCTION

HOW TO RESET THE BUILT-IN IC

When the watch shows an abnormal display or does not properly function, or it does not move at one-second intervals even after being sufficiently charged, follow the instructions below to reset the built-in IC. Then the watch will resume its normal operation.

*If the second hand moves at two-second or five-second intervals, the energy depletion forewarning function should be activated; thus, it is not a malfunction (refer to“CHECKING THE CHARGING STATUS BY THE MOVEMENT OF THE SECOND HAND” on page 12). The watch hands may rotate rapidly because the automatic hand alignment function is activated; however, it is also not a malfunction (refer to “AUTOMATIC HAND ALIGNMENT” on page 19).

*Refer to “THE SCREW LOCK TYPE CROWN” on page 9.
