It mainly refers to a mechanical watch that provides kinetic energy through the natural movement of the wearer's wrist. It rotates with each movement of the wearer's wrist and transmits energy to the mainspring.Provide accurate time, the watch can wind up automatically in your daily life. SYNTHETIC SAPPHIRE MIRROR The mirror is made of synthetic sapphire and has a convex design for high light transmission. The hardness of sapphire is second only to that of diamond. It is resistant to punctures, fractures, temperature and corrosion, making your watch more durable, scratch resistant and light refractive. The convex mirror is designed to better protect the case and bezel. In terms of appearance and decoration, watches equipped with synthetic sapphire convex mirrors are full-bodied and show their rich and noble characteristics. When viewed to refract light, the rounded sapphire crystal flows and tracks light and color. Thanks to the curved convexity that narrows the scene of reflection, it offers a wide field of view and a good depth of field for refraction of the outside world. UP TO 100M WATERPROOF The 100m water resistant watch can not only be worn daily to ward off hand and face splashes and rain, but also used for car washing, showering (cold water only) and swimming. Do not wear your watch while diving or taking a hot shower. This is because the watch is water resistant, but not against water vapor. Any water resistant watch should not be used in hot water (>40C°). This is because water molecules are much more permeable at higher temperatures, and all waterproof watches are designed to be used in cold water. Depending on thermal expansion and contraction, some components of the watch will expand to varying degrees under hot water conditions, resulting in a possible increase in seams. Read more
