The watch strap must be maintained for long-lasting use. Wipe the watch strap from time to time, especially when your wrist sweats. Keep the watch strap clean. Over time, the sweat stuck to it will make the watch strap clean. The strap material is damaged. Therefore, when taking off the watch, you can wipe the strap and chassis with a paper towel to make it more durable. I hope the poster will adopt it~
