More susceptible to damage and premature wear from moisture than a metal bracelet. A leather band may be damaged or exhibit accelerated wear if moisture or perspiration is allowed to remain on or saturate the band. Wipe both the inside and outside of your strap daily with a soft dry cloth to remove collected contaminants. If your strap becomes saturated with moisture either from water or perspiration, be sure to allow the strap to completely dry before wearing the watch again. You should also inspect the buckle and pin connections to ensure the moisture has not loosened any connections on the strap that could result in loss of your watch.
Rubber/Silicone watch straps
Sensitive to perspiration, saltwater, and oil, which are easily absorbed and can cause the strap to crack and then break. Periodic cleaning is recommended. Using an old soft toothbrush and a mild dish detergent and water, thoroughly cleanse the inside and outside of the strap. Completely rinse off any soap residue and then thoroughly dry the strap. If you expose your strap to saltwater, be sure to rinse it with clear water as soon as possible. A rubber protectant may also be used to keep the strap pliable and extend its lifespan.
