Mike starts by discussing one early attempt at automating the winding of a pocket watch. Later, the John Harwood bumper automatic system was industrialized by Fortis of Switzerland during the mid-1920s. Tim showcases an automatic Jaeger-LeCoultre caliber 476 bumper automatic. The Rolex "perpetual" winding system of the early 1930s is discussed; Mike notes the role of the modular Rolex rotor system in creating the "bubble" like case profile of the famed Rolex "bubble back" automatics.
