Essay: Rolex created the auto-rotor movement from the Aegler movement in Hunter watches that featured a “perpetual motion” winding mass. Rolex subsequently patented its first successful perpetually self-winding wristwatch in 1932 and the Bubble Back was introduced in 1933 and featured the first auto-rotor. The reference 3131 is yet another model of a long line of a Oyster Perpetual wristwatches since their inception in 1926
