Check that the second hand of the watch is moving correctly in 1-second interval movement before use. If the second hand is moving in 2-second interval movement or is stopped, this indicates that the watch is not fully charged. When this happens, expose the solar cell to light to recharge or recharge the watch by swinging. When exposing the watch to light, do not place the watch too close to the light source. This can cause the watch to overheat which can lead to a possible malfunction. 2 CONTENTS 1.
1. Features 2. Explanation of Displays and Buttons This analog quartz watch incorporates a solar cell in the watch face. In addition to being equipped with a photoelectric power generation function that converts light energy to electrical energy, it also is equipped with a self-winding power generation function that converts "movement of the watch" produced by swinging the watch while wearing on the wrist into electrical energy.
3. Setting the Time and Date * If the crown is of the screw-tightened type, set the time and date after first loosening the screw. Retighten the screw after the time and date have been set. Minutes Hours Date correction (1st) position (1)Pull the crown out to the time correction position (2nd position) so that the second hand stops at the 0 second position. (2)Turn the crown to set the time. *The date changes at 12:00 AM. Set the time while being careful not to mistake AM and PM.
4. Characteristic Functions of Solar-Powered Watches When the watch becomes undercharged, the warning feature illustrated below is activated and the display of the watch (movement of the second hand) changes.
5. General Reference for Charging Times 6. Charging Procedure (Case of Charging by Illuminating Solar Cell Only) Charging times differ depending on the watch model (type of face, etc.). The charging times shown in the table below are meant to only serve as a rough indicator of required charging times.
Examples: * Charging in close proximity to an incandescent lamp or halogen lamp which can easily reach high temperatures. * Charging in locations that can reach high temperatures such as on an automobile dashboard. * When charging with an incandescent lamp, always make sure to keep the watch at least 50 cm (20 in.) away from the lamp to prevent the watch from overheating. B.
* Charging will not proceed efficiently if the watch is swung too fast or too slow. * When swinging the watch, although the sound of the generator turning can be heard from inside, this is normal and does not indicate a malfunction. * The watch should be swung approximately 200-300 times to ensure 1 full day’s worth of charging when running normally (1-second interval movement). * Charging can be performed even more efficiently by combining charging by exposing the watch to light and charging by swinging.
8. Using the Chronograph
(1) Pressing button A starts and stops the chronograph. (2) Pressing button B when the chronograph is stopped returns the chronograph to the reset display. * If button B is pressed by mistake during chronograph measurement, the chronograph will return to the reset display. Be careful not to accidentally press button B during time measurement. 9.
(1) Pull the crown out to the correcting position (2nd position). (2) Press button A to set the chronograph second hand to the 0 position. Each time button A is pressed causes the chronograph second hand to be corrected in the clockwise direction by 0.2 seconds (1/5 second) at a time. (Pressing button A continuously causes the second hand to advance rapidly.) (3) Return the crown to the normal position.
11. Secondary Battery 12. Using the Tachymeter (When Provided) CAUTION: Handling of Secondary Battery The tachymeter feature is used to measure traveling speed such as that of an automobile. In the case of this watch, the average speed can be approximately determined for a certain distance by measuring how many seconds it takes to travel 1 kilometer (measuring range: maximum 60 seconds). To determine average speed, start the chronograph simultaneous to the start of measurement.
. Precautions For correct use within the design limits of the watch, confirm the level of waterresistance of your watch, as indicated on the dial and case, and consult the table. CAUTION: Water-resistance performance Examples of use There are several types of water-resistant watches, as shown in the following table. The unit "bar" is roughly equal to 1 atmosphere. Indication Moderate exposure to water (washing, kitchen work, swimming, etc.
• Water-resistance for daily use (to 3 atmospheres): This type of watch is water-resistant to minor exposure to water. For example, you may wear the watch while washing your face; however, it is not designed for use underwater. • Upgraded water-resistance for daily use (to 5 atmospheres): This type of watch is water-resistant to moderate exposure to water. You may wear the watch while swimming; however, it is not designed for use while skin diving.
CAUTION: Operating environment • Use the watch within the operating-temperature range specified in the instruction manual. Using the watch where temperatures are outside the specified range, may result in deterioration of functions or even stoppage of the watch. • Do NOT use the watch in places where it is exposed to high temperature, such as in a sauna. Doing so may result in a skin burn.
