Can I wash my watch strap?Stainless Steel bracelet/Mesh strap:
To prevent rust, wipe off the moisture, sweat or any other dirt with a soft cloth promptly.
To wash the band, apply neutral detergent (mixed with water) when stains on the surface are noticeable.
For heavy stains accumulated in the gaps of strap segments, use a small brush to remove them.
During the washing process, protect the watch head from moisture by wrapping it with plastic film. Don’t forget to thoroughly dry the whole watch using a soft dry cloth.
Leather strap:
we do not recommend you wash the leather strap. Any exposure to water will dry the leather and possibly cause damage to the strap. However, a local watchmaker or watch retailer may have cleaning products specifically designed for leather.
Nylon strap:
Always remove the watch face from the wristband. Use lukewarm water together with soap and gently brush the wristband. Leave it to dry flat on a towel.
