The Rolex Datejust’s full name was and still is in truth the Rolex Oyster Continuous Datejust, indicating that also at the time of its intro, it currently included 2 important technologies of Rolex: the Oyster situation, hence being a water-proof watch, and the Continuous winding, meaning that it was an automatic watch with 360 ° rotor.
And it was close to the real edition: a 3-hand watch with a date aperture at 3 o’clock that altered immediately at twelve o’clock at night.
Many thanks to an intermediate equipment’s as well as a spring mechanism, the date disc had the ability to make an instant dive at twelve o’clock at night. The date was simply, all the time.
As you can see, the design of the initial collection continues to be instead near to what we know currently, also if two features was missing: the fluted bezel (the first ones had a coin-style bezel) as well as something that is an actual Rolex’ characteristic: the cyclops– the magnifier over the date home window.
This characteristic component of the actual Datejust just appeared in 1954, after 9 years of manufacturing.
