About Mechanical Watches: Q: What is an automatic mechanical movement? A: Mechanical watches are powered by winding. An automatic mechanical movement features a rotor on the back that spins with the movement of your wrist, winding the watch. If worn for 8 hours or more per day, the watch will continue to run. If left unworn for two days, it will need to be wound and the time reset. Q: Are mechanical watches prone to scratching? A: Our watch cases are crafted from 316L medical-grade stainless steel, and the crystal is made of sapphire, which is second only to diamond in hardness, making it highly resistant to scratches. Q: Are mechanical watches waterproof? A: Yes, our watches are water-resistant. All our watches have a water resistance of 50 meters or more, with the 46mm dive watch rated for 200 meters. Q: My new mechanical watch stopped or is running slow shortly after I started wearing it. What should I do? A: Mechanical watches are powered by winding. Insufficient winding will cause the watch to stop or slow down. Please wind the crown clockwise about 30 times. Q: How should I maintain my mechanical watch? A: If the watch is not worn for extended periods, please wind it every few days. This is because the lubricant oil inside can thicken over time, affecting accuracy. For optimal maintenance, consider using a 24-hour automatic watch winder.
