The main problem with normal quartz watch is we need to change the battery every now and then. In addition, lower priced watches do not have a battery level indicator so the battery can die at any time. Solar watch seeks to solve this by continuously charging the battery through a solar panel on it.
Thus, it's easily recharging itself just by having its owner wear it for around! That's how convenient the solar watch is. If you're looking for a good and affordable solar watch to try for yourselves, check out these 10 Best Solar Watches Under $200.
