Stainless Steel ConstructionStainless steel is a strong and durable material that can withstand daily wear and tear, including scratches and abrasions. Moreover, it is non-allergenic and does not cause skin sensitivity. Its low allergenicity makes stainless steel a safe and comfortable choice. Additionally, its excellent corrosion resistance allows stainless steel watch straps and cases to maintain their appearance and performance in various environments.

100M Waterproof: With a water resistance of up to 100M you can easily handle most situations in life, such as washing hands, rain, swimming(please tighten the crown when going into the water). It is not recommended to wear the watch while diving or taking a hot shower. Water vapor will corrode the waterproof rubber ring and most watches are not protected from water vapor.
