Rolex 3235

History: In 2018, Rolex released the Calibre 3235, a new-generation movement entirely developed and manufactured by Rolex. A consummate demonstration of Rolex technology, at the forefront of the art of watchmaking, this self-winding mechanical movement offers fundamental gains in terms of precision, power reserve, resistance to shocks and magnetism, convenience and reliability. It incorporates the Chronergy escapement patented by Rolex, which combines high energy efficiency with great dependability. Made of nickel-phosphorus, it is also insensitive to magnetic interference. The oscillator, the true heart of the watch, has a blue Parachrom hairspring. Manufactured by Rolex in an exclusive paramagnetic alloy, the Parachrom hairspring is up to 10 times more precise than a traditional hairspring in case of shocks. It is also fitted with a Rolex overcoil, ensuring its regularity in any position.

Alfred Davis and his brother-in-law Hans Wilsdorf founded Wilsdorf and Davis, the company that would eventually become Rolex SA, in London, England in 1905. Wilsdorf and Davis' main commercial activity at the time involved importing Hermann Aegler's Swiss movements to England and placing them in high-quality watch cases made by Dennison and others. These early wristwatches were sold to jewellers, who then put their own names on the dial. The earliest watches from Wilsdorf and Davis were usually hallmarked "W&D" inside the caseback.
