The present invention relates to a watch holder system, which is worn on the back side of a hand, comprising a casing, an elastic cord, and a buckle. The casing is provided with two holes passing through from the front end to the back end and accommodating the elastic cord. The lower side of the casing is concave to match the surface of the back side of the hand. By the wearing position of the watch holder system, a novel and beautiful effect is created. In use, the watch will not be covered by a long sleeve, thus allowing for unhindered reading of the displayed time.
