The band I am not sure. However, my SBSS watch usually ends up in the shower with me as I forget to take it off most times. Ends up getting nice and clean with the rest of me. I've been doing that since I had the original S0 watch. Have done it with the S0, S2, S3, and now the S4. Never had an issue with water getting in or anything. When I am done I will take the band off and dry it real good along with the part of the watch where the band slides in.
