Original von Prof. Rolex
Ob Rolex den Namen „Cosmograph“ für seine Chronographen in Anlehnung an die alte Wissenschaft der Kosmographie (Lehre von der Beschreibung der Erde und des Weltalls) gewählt hat, ist aber nur eine Vermutung.
Im Lichte dieser Aussage im Dowling/Hess aber nicht unwahrscheinlich:

"Despite the success of the 25-year-old patent for the scew-down Oyster crown, Rolex introduced the "Super Oyster" crown. This was a non screw-down crown whose impermeability was supposedly ensured by a system of gaskets and precision tolerances. Called in some of Rolex's adverstisements by the bizarre name of the "phantom crown", it was introduced on the model 6062, (automatic/day/date/month/moon phase)..." ... dann einige Ausführungen zu den Problemen mit der neuen Krone ... und dann die Fußnote: "When first launched, this watch was named the "Cosmograph", a reference to the moon and the stars on the moon dial. The name should have died with the short live of the model, but Rolex retained the name and subsequently used it on Chronograph watches."
