It charges using sunlight or other light, eliminating the need for regular battery replacement. A single full charge lasts for approximately two years (with power save activated). Because it uses light as its energy source, storing it in a location where it can be easily exposed to light will ensure it remains charged and ensure stable use. [Automatic time correction "Radio-controlled clock"] The time and calendar are automatically corrected by receiving standard radio waves transmitted from an atomic clock, which is said to have an error of 1 second per 100,000 years. The clock receives radio waves transmitted from two stations, Fukushima and Kyushu, to provide accurate time. [REGUNO] REGUNO is a simple, affordable standard watch.

[About charging Solar Tech] Charge by exposing the dial to direct sunlight or fluorescent light. Tips for proper charging: Even when you take off the watch, if you place it in a bright place where sunlight hits the dial, the watch will continue to work properly. Charge it by exposing it to direct sunlight once a month. If storing it in a place out of light, be sure to fully charge it before storing it. Insufficient charge warning function: Charge when the hands start moving every 2 seconds. *You can also check the instruction manual (PDF) on the manufacturer's website.
