Seiko 5M43 Manual - Page 18

English Notes: 1. To allow easy reading of the second hand, we recommend that the button be pressed when the second hand is at the 12 o'clock position. When the second hand points to "LO", the capacitor has a power reserve of between 1 and 2 days (Cal. 3M22) / 2 and 4 days (Cal. 5M42/5M43). 2. You can immediately press the button again to recheck the power reserve one more time. To do so a third time, however, wait until the second hand resumes normal movement before pressing the button again. 3. When the second hand moves at two-second intervals, the power reserve is very low and the indicator does not function. See the next section, which explains the Energy Depletion Forewarning Function. 4. Immediately after the watch is swung to charge the capacitor, the second hand may not properly indicate the power reserve. Please check after putting the watch on your wrist. 5. Precaution on see-through case-back models: If your watch has a glass case back, do not expose the case back to strong light such as direct sunlight or an incandescent light at close range, as this may temporarily increase the power consumption of the watch circuit, thus reducing the power reserve in the capacitor. This condition, however, will be corrected when the case back is turned away from the light. 18
