Using this Tissot watch is easy. Just put it on your wrist like any other watch. To keep it in good shape, avoid hitting it against hard objects as the sapphire crystal, though scratch - resistant, can still be damaged. When the watch shows that the battery is at the end of its life, take it to a professional watch repairer to replace the battery. Keep the watch away from water as much as possible, even though it may have some water - resistant features. Clean the watch regularly with a soft, dry cloth to maintain its shine. Also, because the mother - of - pearl dial is natural and unique, don't try to clean it with harsh chemicals, as it may affect its appearance.
