“Rolex Watch History”
Rolex watches were founded in the late 1920's. Since then Rolex watches have been responsible for most of the horological innovations of the last century: first wrist watch, first automatic watch and the first waterproof watches , Rolex watches specialize in the production of high-precision wristwatches and chronometers.
1) 1st Wrist watch???????
2) First Self Winding Source: Wikipedia
The first "self-winding," or "automatic," wristwatch was the invention of a British watch repairer named John Harwood in 1923. This type of watch allows for a constant winding without special action from the wearer: it works by an eccentric weight, called a winding rotor.
3) 1st Dive watch Source: Wikipedia
Neither Panerai, Blancpain, nor Rolex can claim to have produced the first dive watch, as the Omega "Marine," introduced in 1932, probably deserves that title.
The Truth seems very flexible, Thought I should try and be factual but it is not easy
