To use this Tissot watch, simply put it on your wrist using the interchangeable quick - release bracelet. You can change the bracelet whenever you want to match different outfits. When setting the time, refer to the instructions for Swiss Quartz movements. For daily use, avoid exposing the watch to extreme temperatures, water (although it may have some water - resistance, check the specific details), and strong impacts. To keep it looking great, clean the case and bracelet regularly with a soft, dry cloth. If the watch face gets dirty, use a slightly damp cloth to gently wipe the scratch - resistant sapphire crystal. If you have any problems with the movement or other parts, it's best to take it to a professional watch repair service.
