Using your Citizen Luxury Eco - Drive EM1143 - 81X is a breeze. Just wear it on your wrist like any other watch. To keep it running, expose it to light regularly as it's an eco - drive watch. When you're out for a swim or in the rain, you don't have to worry as it's water - resistant up to 50 meters, but avoid high - pressure water like diving with scuba gear. For cleaning, use a soft, dry cloth to wipe the case, bracelet, and crystal glass. If it gets dirty, you can gently clean it with a mild soap and water solution, then dry it thoroughly. Keep it away from strong magnetic fields as they can affect the timekeeping accuracy. If you're not going to wear it for a long time, store it in a cool, dry place in its watch box.
