Seiko 7D56 Manual - Page 3

English FEATURES SEIKO KINETIC Cal. 7D46/7D48/7D56 is an analogue quartz watch equipped with the Kinetic technology developed by SEIKO. It generates the electric energy to power the watch, utilizing the movement of your body, and stores it in the rechargeable battery, which requires no periodical replacement unlike conventional button-type batteries. The watch is provided with the following additional functions. POWER SAVE FUNCTION AND TIME RELAY FUNCTION In order to conserve the stored electrical energy, the watch automatically enters power save mode to stop the hands from moving approximately 24 hours after the watch is taken off the wrist. When you decide to wear the watch again, simply swinging the watch several times will awaken it and the hands will indicate the correct time to resume normal operation. ❖ The time retrieved by the time relay function may include a certain amount of time loss or gain within the range of accuracy of the watch ( 15 seconds per month). ❖ In a case that the fully charged watch enters the power save mode, the time relay function of the watch remains operable for approximately four years. 4 PERPETUAL CALENDAR FUNCTION ● Once set, the calendar automatically adjusts for odd and even months including February of leap years. (Exceptionally, the manual adjustment at the end of February is required for the years that are divisible by four but are not leap years, which comes only once every hundred years, for example, the year 2100.) ✽ It takes approximately two seconds for the calendar to change its display. However, it may take two minutes if the temperature is low or the stored electrical energy is being depleted. ● While the watch is in power save mode, the perpetual calendar continues to function. ● Even if the watch is completely stopped due to a shortage of stored electrical energy, the calendar can be manually adjusted by simple procedures. CAUTION ● The movement of your arm while the watch is worn generates electrical energy to power the watch. Even if the watch is worn on your arm, it will not be charged while your arm is not in motion. ● It is recommended that the watch be worn on your wrist daily for at least 10 hours. 5 English
