A:Answer Honestly, i didnt read and dont know if there are any instructions on the papers, i just clean it with water and liquid soap or shampoo, generally during bath time and later dry down on me or mostly when i put the watch on charge in like 20-30 min, i even got sand, nutella, skin lotions, parfums, and works for me, mine is perfect after 2 months of use (doesnt get bad odors unless you train and sweat and dont clean or wash it) ..
