Spinone italiano

Return air vent Rolex was the first watch manufacturer to devise and patent the rotor system that is still used today. They called it the Perpetual and it was part of the popular Oyster line created in the early 1930s. Emile Borer was the Rolex technician who came up with the system, but he was not the first to develop a rotor. That distinction goes to Swiss watchmaker, Abraham-Louis Perrelet as long ago as 1770. This was quite the invention because it wouldn’t be until much later in time that wrist watches were worn and there just wasn’t enough physical movement with a pocket watch to make it a feasible way to move the rotor and wind the mainspring. hilda morath
