Mechanism: The Hunter series of movements was introduced in 1923 and designed to replace the earlier Rebberg series. In 1935 Rolex complemented the design with the "Superbalance" component (for which they obtained a patent). The 10½ Hunter was named as 10½ is the size in lignes (23.7mm) and “Hunter” being the layout of the watch design, meaning that the winding crown was at 3, as in a hunter pocket watch (one with a lid that closed over the dial), rather than at 12 as in an open-face pocket watch. Rolex and Aegler made continuous improvements to this line of movements from 1923 when it was introduced until 1969 when it was finally retired

This late version of the Hunter was augmented to pass chronometer certification. The augmentations took the Hunter movement of the 1950s from 17 to 18 jewels. Like all Hunters, this movement has no date function. This version has the second hand in a "sub" or subsidiary location below the main dial. Later versions of the movement are known as Calibre 700.

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.

Type: The Rolex Thunderbird Datejust boasts, perhaps, one of the most intriguing histories in the entire Rolex catalog. Its nickname "Thunderbird" was inspired by the US Air Forces aerobatic unit the Thunderbirds. Specializing in daring flights and mid-air tricks, the Thunderbirds quickly took the aeronautical world by storm.

A vintage ad for the Turn-O-Graph ref. 6202 explains, “…now the simplest of all ways of timing has been invented. It is built into a wrist-watch called the Rolex Turn-O-Graph. This new principle consists of an extra rim or bezel round the watch face. This rim is marked from zero to sixty and is easily turned by hand. To time an operation or even, all you have to do is align the zero mark on the rim with the second, minute, or hour hand of the watch. Thereafter, at any moment, you have an immediate record of the time elapsed.”
