Rolex introduced a new generation of the Datejust 36 at BaselWorld 2018. It is initially offered in either steel & yellow gold or steel & 'Everose' rose gold, and it features a subtly resigned case paired with a new movement - caliber 3235.
As is customary with the Datejust it is available in a myriad of configurations; reference 126233 is done in a combination of stainless steel & yellow gold and has a fluted bezel.
Calibre 3235 is a new generation movement, entirely developed and manufactured by Rolex for a superlative level of performance. Certified as a Swiss chronometer by COSC (Swiss Official Chronometer Testing Institute), it is tested a second time by Rolex after being cased to ensure that in everyday use it satisfies Rolex’s criteria for precision, which are twice as exacting as those for an officially certified chronometer. This control of the final precision of the assembled watch is carried out using a methodology and high-technology equipment specially developed by Rolex. Caliber 3235 features the new Chronergy escapement and Parachrom hairspring.
