This Citizen men's watch features clean lines that are sure to make it a timeless classic. It comes with a chronograph function, date display, and a sleek black dial. The watch is crafted with a stainless - steel case and bracelet, offering both durability and style. Powered by the advanced Eco - Drive technology, you'll never have to worry about changing the battery again. The 41mm case is covered with mineral crystal glass for scratch resistance. It's water - resistant up to 100 meters or 10 Bar, making it suitable for swimming, snorkeling, and showering. With a multi - dial design and calibre B642, this watch is a perfect blend of functionality and elegance.

Using this Citizen watch is easy. To operate the chronograph, there are buttons on the side of the watch. Press the top button to start or stop the stopwatch, and the bottom button to reset it. The date will update automatically each day. When it comes to water resistance, it's great for swimming and snorkeling, but avoid high - pressure water situations like diving with scuba gear. For maintenance, clean the watch regularly with a soft, dry cloth. If the watch gets wet, dry it thoroughly. Store the watch in a cool, dry place when not in use. And since it's Eco - Drive, just expose it to light regularly to keep it powered.
