Notes: This version of the Datejust appeared in the 2000's along with the 2235 movement. It features the two-tone look with a case and bracelet made primarily from stainless steel but with the case augmented by an 18K yellow gold bezel. The bezel is typically smooth (not fluted), though there are versions with diamond bezels. The dials can be white, champagne, mother-of-pearl or olive green (yes, really). The hour markers can be indices, roman or diamonds. It is typically marketed as a lday's watch thought the case size is 31mm making it technically a unisex watch. It can come with the 3-link or 5-link (Jubilee) bracelet.

Mechanism: The 2235 is an update to their already accurate and reliable Cal. 2135. The calibre 2235 is a self-winding mechanical movement entirely developed and manufactured by Rolex. Like all Rolex Perpetual movements, the 2235 is a certified Swiss chronometer, a designation reserved for high-precision watches that have successfully passed the Swiss Official Chronometer Testing Institute (COSC) tests. Its architecture, in common with all Oyster watch movements, makes it singularly reliable. This movement features date and date quickset functions.

This mechanism does have hacking capability.

Family Notes: The Datejust emerged in 1945, introducing the watch world to the innovative automatically changing date window. This feature made watch history and has since made the Datejust one of Rolex's most successful models. The ladies model that was introduced a few decades later has enjoyed a large amount of success as well, thanks to its functional yet luxurious design. The Rolex Datejust is the modern archetype of the classic watch, thanks to aesthetics and functions that transcend changes in fashion. Aesthetically, the Datejust has spanned eras, while retaining the enduring codes that make it, notably in its traditional versions, one of the most recognised and recognisable of watches.

Originally named the Jubilee Datejust, Rolex Datejust history began in 1945 when Rolex released the model for the company's 40th Anniversary. It was a direct descendant of the Bubbleback and included a date function, which was placed at the 3 o’clock position on the face. The Datejust had a coin-edge bezel, which later became the flutted bezel. It was the first watch to show the date automatically and also the first to change the displayed date at exactly midnight. The Datejust was innovative, unique, and different than any other watch offered at that time.

The history of Rolex Datejust begins with the first Datejust, the Jubilee Datejust Model 4467, which was only available in 18k gold and had a small bubbleback winder with a deeply domed back. In the 1950's, the Oysterdate joined the Datejust family, coming in two sizes. Although the Datejust originally consisted of three case parts, it was quickly updated to just two. Another major update was the addition of the Cyclops lens in 1954. Today this lens is standard to Rolex watches and even part of the brand’s signature. Before 1954, however, no one had used a magnifying bubble on the lens right above the date. Then, in 1957, a new, lighter, slimmer movement, the caliber 1065, allowed for a flattened case back in place of the old domed one. That same year, the Datejust became available in Steelium (stainless steel) in addition to the original gold. Other changes over the years included a flat dial (rather than curved) and the Rapid Date Change (aka quickset) feature.

The fact that Rolex Datejusts are still purchased and worn today is a testament to their enduring respectability and timelessness. To understand the Rolex Datejust history, pictures can be worth a thousand words. Seeing pictures of multiple presidents and other powerful people wearing the Rolex Datejust shows the importance and significance of this watch.
