Did you know whre the name ROLEX came from?

[Rolexwatch]

I didn't. This might be true:

In 1906 Henry Royce was advertising his cars that he had partnered with Charles Rolls announcing that they were so quiet that at 40 mph people may be able to hear a watch ticking. At an after performance party at the London Brixton theater and Opera house,
Davis, owner of a Rolls Royce, joked with the car makers telling them they were able to hear a watch ticking inside of their cars but not one of his. Davis came up with the idea to use part of the Rolls Royce name, symbol of class, elegance and reliability.
His partner was against removing his initial but Davis matched the Timex and Rolls Royce name, ROLLSROYCETIMEX and this name was more acceptable to Wilsdorf and Rolex became the brand we love today.
