TeamSky Men's Automatic Mechanical Watch, Waterproof, Stainless Steel, Luminous, Large Dial, Date Display, Father's Day Gift (Black Dial, Silver Band)

[Hand-wound watch] Mechanical watches, due to their construction without electronic circuits, will have a few seconds of error per day. To maintain stable accuracy, use the watch with the mainspring fully wound. Hand-wind the watch once a day, preferably at the same time. Once the mainspring has been wound (about 20 revolutions), the watch can be started. [Durable & Waterproof] The high-hardness mirror and steel case and bracelet materials provide excellent wear resistance, allowing for reliable daily use. This watch is water resistant to 30 meters (3 ATM/98 feet), meaning it can withstand underwater pressure of 30 meters. Its water resistance is sufficient for everyday use and can withstand splashes, raindrops, and sweat. However, it does not protect against hot water, hot water, or steam. The watch cannot be washed away by currents. Do not wear it while diving or swimming. [Outstanding Appearance] The large 41mm dial adds presence and a sense of luxury to the entire watch. The window on the left side of the dial displays the date. (Note: Mechanical watches have many small parts and are vulnerable to impacts, so they must be handled with care. Mechanical watches are made up of delicate parts that move together, so please store them properly when not wearing them to avoid dropping them and damaging them.) [A Great Gift] With its intricate and detailed openwork engraving and unique Roman numerals, this is the perfect gift. This retro and luxurious watch is perfect for the gentleman and experienced man. It's a perfect gift for Father's Day or an anniversary, and shows great consideration. TeamSky has always been committed to providing customers with high-quality products and services.
