The Turn-O-Graph, a reliable instrument.

The Oyster Perpetual Turn-O-Graph was launched in 1953. Its graduated, bidirectional rotatable bezel enables the wearer to measure elapsed time between one and 60 minutes. With this technical evolution of the original Oyster Perpetual, the Turn-O-Graph became a simple, robust and practical instrument for everyday life.
