Why do I find that my wrist turns black after wearing the strap for a long time?

If you wear the bracelet for a long time, you will find your wrist becomes black. What is the reason? Whether it is a metal strap or a belt strap, there is a benchmark. Leather watchbands have special quality requirements that cannot be discolored or faded, but for metal watchbands, they belong to the category of surface electroplating, and only the bonding strength of the electroplating coating is specified. Leather straps are more likely to fade and stain after being soaked in water, but generally the inner side of leather straps is more light-colored. Silver straps will not fade. Only some metal straps with coating will fade. Such straps are usually low-end products. The surface of the watchband with electroplating, after long-term use, the surface will be rusted, and severely, the surface will be mottled with green rust, and these rust classes can also be'transferred' to the wrist. Most of the reasons for wearing a watchband to turn black are caused by dust and sweat. This depends on personal circumstances, such as the working environment, the nature of the work, whether the person is prone to sweating, and the form of wearing the watchband. The hollowed-out watch band is easier to 'hide dirt and dirt'. Dust, fiber and mixed sweat will fill all the gaps of the watch band. In the summer, once the wrist sweats or gets wet, the dirt will be dissolved out. The sticker is attached to the skin of the wrist to form a black spot-like mark.
