This kit is for watches with round dials between 16mm and 50mm in diameter; It is only suitable for watch back covers with pry holes, not for back covers with screws. It is difficult for a novice to control the speed and force of the downward pressure of an ordinary watch press tool. Our watch press tool uses a rotating handle to adjust the speed and force of the press, easy to use even for novices. The watch press is made of metal, which is very sturdy; the mold is plastic, equipped with a cleaning cloth, which can be placed in the middle of the watch glass face and the mold when in use, effectively avoiding scratching the watch glass. Pry knife for opening the back cover of the watch; Tweezers for removing and installing the battery.
