English 0 5 FEATURES SEIKO KINETIC Cal. 5D88 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 buttontype batteries. The watch is equipped with a direct drive indicator that constantly displays how long the watch will keep operating. The direct drive indicator also dynamically displays the electric power generation status while charging the watch. In addition, the watch is equipped with a 24-hour hand, date hand, day hand, and moon phase display. 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. ● If you do not wear the watch for more than the continuous operating time that it displays, charge the watch as necessary so as not to stop operation of the watch until the next time you wear it. Refer to "How to charge and start the watch" for further details.
