English CAL. 8R28 CHARACTERISTICS OF A MECHANICAL WATCH (self-winding type, automatic winding type) ● This mechanical watch operates using power obtained from a mainspring. ● If the watch is completely stopped, manually turn the crown approximately 20 times to wind up the mainspring to start the watch. ● While loss/gain of a quartz watch is indicated by a monthly or annual rate, accuracy of a mechanical watch is normally indicated by a daily rate (loss/gain per day). ● Normal usage accuracy of a mechanical watch varies according to conditions of use (time period that the watch is worn on the wrist, temperature environment, hand movement, and winding state of the mainspring). ● When the watch is affected by strong magnetism, it temporarily gains or loses time. If the watch encounters a strong magnetic field, the parts of the watch may be magnetized. In this case, repairs such as removal of magnetism are required. Contact the retailer from whom the watch was purchased.
