Movement: Japanese automatic mechanical watch movement, equipped with 24 rubies, self-winding movement 40 hours of kinetic energy storage. Case: 316L steel sapphire crystal case Strap: Belt For mechanical watches: Q: What is an automatic mechanical movement? A: The mechanical watch is driven by the winding, and the automatic mechanical movement has an automatic winding rotor on the back, which will rotate in response to the wrist swing, thus winding the mechanical watch. If you wear it for 8 hours or more a day, the mechanical watch can keep running for one day. If you don't wear it for two days, you need to re-adjust the correct time after winding. Q: Will the mechanical watch be easily scratched? A: Our case is made of 316L medical grade steel, and the surface glass is made of sapphire crystal, which is second only to diamond in hardness, so it is relatively easy to scratch. Q: Is the mechanical watch waterproof? A: Waterproof, all our watches have a waterproof performance of more than 50M, and the 46mm diving watch has a waterproof rating of 200M. Q: I just bought a mechanical watch, but it stopped soon after wearing it/time is slow, what should I do? A: The mechanical watch is driven by the winding. If the winding is not enough, it will stop/slow down. Please turn the crown clockwise to wind the watch 30 times. Q: How to maintain a mechanical watch? A: If you do not wear the watch for a long time, please wind it every few days, because the lubricating oil in the watch will be left standing for too long, which will cause the running time to be inaccurate. For better maintenance, a 24-hour self-winding watch case is available.
