Using this Citizen watch is a breeze. Just put it on your wrist and fasten the push-button buckle. The watch gets power from light thanks to its Eco-Drive technology, so you don't need to worry about changing batteries often. It has a 6 - month power reserve, but it's a good idea to expose it to light regularly. For accuracy, it's set to be within ±15 seconds per month, so you can rely on it for timekeeping. When it comes to water resistance, it can handle splashes and short swims up to 50 meters, but avoid wearing it in hot tubs or while diving deeply. To keep it looking great, clean the stainless - steel case and bracelet with a soft, dry cloth. If the mother - of - pearl dial gets dirty, you can use a slightly damp cloth and gently wipe it. Always store your watch in a cool, dry place when you're not wearing it.
