Alright, so now that that was just addressed, how about we discuss how you are supposed to charge your device with the sunlight. Well, first off, it is important to note that if you regularly wear your timepiece outside and in direct contact with sunlight, you probably will not need to go out of your way to charge it very often. If you do notice that your solar energy timepiece is getting low on battery life, with some models providing you an indicator, you can quickly charge it up.
To do so, try to find an optimal location where sunlight is available. This could be on a window ledge, for example. In warmer climates, it should take roughly 20 hours to fully charge. When it gets colder, this time could end up tripling.
