[. . . ] 3 4 6 9 10 11 12 13 14 For the care of your watch, see "TO PRESERVE THE QUALITY OF YOUR WATCH" in the attached Worldwide Guarantee and Instruction Booklet. 2 FEATURES English SEIKO KINETIC AUTO RELAY Cal. 7S55 is an analogue quartz watch equipped with an Automatic Generating System developed by SEIKO. It generates the electric energy to power the watch, utilizing the movement of the arm, and stores it in the KINETIC ELECTRICITY STORAGE UNIT (KINETIC E. S. U. ). So, the watch does not use a conventional button-type battery and does not require battery replacement. [. . . ] In this case, charge the watch referring to "ENERGY DEPLETION FOREWARNING FUNCTION", and then, follow the procedure below. CROWN Pull out to the first click. 4 w * Pull out and push in within one second. Push in to the normal position. * The hands will stop as the power save function is activated. Note: If your watch has a screw lock type crown, turn the crown counterclockwise to unscrew it, and then, pull it out. After using the crown, push it back in to the normal position, and then, turn it clockwise to screw it in completely. English Caution: Do not pull out the crown to the second click while the power save function is in operation. Otherwise, it is turned off, and the time data retained inside the watch will be erased, thus disabling the time relay function. 5 English TIME RELAY FUNCTION q While the power save function is working, the built-in IC continues to compute the time though the hands have stopped. As a certain amount of electricity is generated by swinging the watch, the time relay function is activated, and the hands are adjusted automatically to the time retained inside the watch. q If the watch is charged fully as the power save function is activated, the time relay function remains operable for approximately four years. How to activate the time relay function Caution: Do not pull out the crown to the second click before activating the time relay function. Otherwise, the time data retained inside the watch will be erased, thus disabling the time relay function. q Swing the watch from side to side for 2 to 3 seconds. 6 1. The hour and minute hands move quickly to indicate the current time computed by the IC. English 2. The second hand moves quickly to indicate the current second, and then continues moving at one-second intervals. Notes: 1. Swing the watch from side to side, making an arc of about 20 cm. Swing 4 to 6 times at a rate of twice a second. No additional benefit is obtained by swinging the watch longer or with greater vigor. When the watch is swung, the oscillating weight in the generating system rotates to drive the mechanism. As it rotates, it gives out a sound, which is not a malfunction. The watch is equipped with a system to prevent overcharge. Even if it is further swung after being fully charged, no malfunction will result. Wear the watch daily for at least 10 hours. Even if the watch is worn on your arm, it will not be charged while your arm is not in motion. English POWER RESERVE IN YOUR SEIKO KINETIC WATCH q The electric energy generated while the watch is worn on your wrist is stored in the KINETIC E. S. U. It is a power source completely different from conventional batteries for watches, and therefore, this watch does not require battery replacement. q Power reserve guideline for the KINETIC E. S. U. · You can estimate the power reserve accumulated in the KINETIC E. S. U. from the manner in which you wear the watch. · Using the manual power save function as often as possible is an effective way to conserve the power reserve. 11 English 12 Wearing the watch continuously for 12 hours will accumulate approximately one and a half additional days of power reserve. If you wear the watch every day for 12 hours over a period of a week, approximately 10 days of power reserve will be secured in the KINETIC E. S. U. , which will keep the watch operating for approximately 2 months when the hands are stopped by the power save function. q Precautions for those only wearing the watch occasionally If you use the watch only occasionally, it is likely that, when you decide to use it, you will find the hands have stopped and the power save function has been activated. Before wearing the watch, be sure to use the time relay function to awaken the watch following the procedure in "How to activate the time relay function". * To use the power reserve more efficiently, it is recommended that the manual power save function be used as often as possible when you remove the watch from your wrist. REMARKS ON THE KINETIC E. S. U. q Precaution Do not pull the crown out to the second click to stop the hands with the intention of saving the energy stored in the KINETIC E. S. U. [. . . ] Turn the rotating bezel to align its " mark with the minute hand. " Start Elapsed time 30 minutes have elapsed. 2. Read the number on the rotating bezel that the minute hand points to. Note: For some models, the rotating bezel rotates only counterclockwise. 13 SPECIFICATIONS English 1 2 3 4 5 6 Frequency of crystal oscillator . . . . . . . . . . . . . . . . . . .
