Rolex developed the Oyster case in the 1920s. The name ‘Oyster’ refers to the incredible water resistance of the case. A few years later, the brand patented the self-winding movement as the ‘Perpetual’. This Oyster Perpetual with the reference 1003/8 was presented to Herbert E. Grant for his twenty-fifth anniversary at Coca-Cola Boston.
