With perforated edges, these watches resemble a stamp, giving an alternative design to the traditional round watch shape. If you're looking for something a little different, S.T.A.M.P.S watches may be just what you'd like! The size is 42mm x 42mm x 9mm, and the watches have a three hand mechanism with a replaceable battery. Each strap comes with a snapper to snap the watch face in place. Straps and faces are sold separately.
