Special care and maintenance will allow your watch to function properly for longer and revive the luster of each creation. Please always check that the crown is well pushed in and/or screwed down. For ceramic or metal straps, clean with soapy water, rinse well, and dry with a soft cloth. For leather or satin straps, polish it using a soft cloth. A watch must never be worn in a sauna, a shower, or a bath, as hot water may damage its water-resistance seals. CHANEL Style # H6401
