(The time difference can be adjusted in increments of 1 hour.) After selecting the time zone, if it is within the reception range of radio signals, you can leave the watch to receive the radio signal to set it to the precise time.

CAUTIONS ・ T he watch may display the wrong time if it fails to receive radio signals properly because of interference. The watch may also fail to receive radio signals properly depending on the location or radio wave receiving conditions. In this case, move the watch to another place where it can receive radio signals. ・ W hen the watch is out of reception range, its accurate quartz movement (loss / gain: ±15 seconds per month on average) will continue to keep the time. ・ T he time signal transmission may be stopped during maintenance of the facilities of each transmitting station or because of a lightning strike. In such a case, see each station’ s website for further information or contact SEIKO CUSTOMER SERVICE CENTER. ・Websites of transmitting stations (as of December 2017) Japan: NICT (Japan Standard Time Group) http://www.jjy.nict.go.jp/ China: NTSC http://www.ntsc.ac.cn The U.S.A: NIST https://www.nist.gov/pml/time-and-frequency-division/radio-stations/wwvb...

However, for various reasons such as long-term use or usage conditions, the capacity or recharging efficiency of the secondary battery may gradually deteriorate. Worn or Lumibrite contaminated mechanical parts or degraded oils may also shorten recharging cycles. If the efficiency of the secondary battery decreases, have the watch repaired. Lumibrite is a luminous paint that is completely harmless to human beings and natural environment, containing no noxious materials such as radioactive substance. NOTICE Lumibrite is a newly-developed luminous paint that absorbs the light energy of the sunlight and lighting apparatus in a short time and stores it to emit light in the dark. Remarks on replacing the secondary battery For example, if exposed to a light of more than 500 lux for approximately 10 minutes, ・ Do not remove the secondary battery yourself. Lumibrite can emit light for 3 to 5 hours. ・ Replacement of the secondary battery requires professional knowledge and skill. Please ask a watch retailer for repair. Please note, however, that, as Lumibrite emits the light it stores, the luminance level of the light decreases ・ When replacing the secondary battery, make sure that the exclusive secondary battery for this watch is gradually over time.
