It can take advantage of even very subtle light for timing accurately.
As long as your watch is exposed to light, the power cell will continue to recharge the battery. When fully charged, the battery provides enough power to operate the watch for 1-6 months – even if the watch has been in darkness. If your watch loses power we recommend you place watch in daylight for a full 5-6 hours (direct sunlight is the strongest source of energy for recharging)
