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.
Since the introduction of the very first Rolex Datejust watches the name "Datejust'" never appeared anywhere on any Rolex watches. Only during the production of the reference 5030 did the word "Datejust" begin to appear on the dials of Rolex date displaying watches.
The reference 5030 is also referred to as the ‘Ovettone’ among watch collectors.
