Reputation depends on quality, quality comes from Hard!
Zirocnia Ceramics:
1. When the ceramic watchband is dirty due to long-term wear, just use a small toothbrush and soap to gently scrub.
2, it is best to place the desiccant in the place where the watch is placed, but avoid using chemicals such as mothballs and insecticides.
3, different watches should be worn in different occasions; if sports, it is best to use sports watches with excellent waterproof and shock resistance.
4. If there is a watch with a WATERER RESESTENT or 3ATM on the cover, the water resistance is limited to water spray or light rain without pressure.
5, special reminder: any watch should not be worn in warm water or bathroom, even if your watch is a waterproof watch, because the seal of the watch is rubber is easy to age due to heat, and the surrounding water vapor molecules are relatively small, it is easy to penetrate into the case , causing damage to internal machinery.
6, medium and high-end watches are recommended to do the corresponding maintenance every two to three years, replace the waterproof components, check the travel performance and movement power consumption, cleaning the movement and maintenance appearance, such maintenance services will effectively extend your watch usage time.
