ABSTRACT:
A wrist-worn tennis scoring device including a back having wrist mounting straps and a pivot post to receive a stack of five discs, the first two of which are rotatable and have separately colored index tabs which project outwardly from the disc peripheries, the tabs being rotatably alignable with score figures on the fifth or face disc. The third disc is rotatable and has a series of numbers in a circle around its periphery and between the third and face discs is a rotatable, transparent fourth disc having a second set of numbers in a circle concentric with the circle of numbers on the third disc. The face disc has a pair of diametrically opposed holes through which the numbers on the third and fourth discs can be observed. The tab indicator positions record the player point scores within each game and the numbers appearing in the face disc windows record the number of games scored in each set by each player.
