What makes the highly popular Lady-Datejust 28 watch such a hot favourite among women?

In 1945, Rolex introduced the Oyster Perpetual Datejust to commemorate its 40th anniversary. It was the first self-winding waterproof chronometer wristwatch to display the date in a window at 3 o’clock on the dial. The first women’s version of the date chronometer known as the Oyster Perpetual Lady-Datejust was launched in the late 1950s. It fused classic sophistication with functionality into a smaller, daintier timepiece for a woman’s wrist. Over the decades, Rolex produced Lady-Datejust watches in various sizes until when it launched the Lady-Datejust 28 in 2015. Available in a 28mm Oyster case, the Lady-Datejust 28 is a firm favourite among modern women for its ability to bring them effortlessly from boardroom to the ballroom. Using the Lady-Datejust 28 in yellow Rolesor (a combination of Oystersteel and 18 ct yellow gold) as an example, we list the important figures of the watch that one should know by heart.

2 — NUMBER OF METALS USED TO CRAFT THE EXTERIOR OF THE LADY-DATEJUST 28
Oystersteel is reliable and robust, while gold is shiny and precious. That is why Rolex has been combining the use of these two metals in its watches since the early 1930s. Known as Rolesor—the use of gold and steel, with their contrasting colours and radiance, on a single Rolex watch—this metallic combination is well-loved by consumers, a prominent pillar of the Oyster collection, and employed in the Lady-Datejust 28.

3 — WHERE THE ICONIC CYCLOPS LENS IS LOCATED AT
For its earlier watch releases, Rolex introduced a date indicator via a disc in a window located at 3 o’clock on the dial. In 1953, the Cyclops lens, a domed shape that magnifies the date for better legibility, was added to the sapphire crystal. It has since become one of the iconic and instantly recognizable characteristics of the Oyster Perpetual Datejust collection, of which the Lady-Datejust 28 is a part of.

5 — NUMBER OF PIECES IN EACH LINK OF THE ACCOMPANYING JUBILEE BRACELET
Equipped with the Jubilee bracelet, the Lady-Datejust 28 always sits beautifully and comfortably on the wrist of the wearer. First designed in 1945, the five-piece link metal bracelet was made especially for the launch of the original Oyster Perpetual Datejust. Ergonomics have taken into consideration for its creation with extra attention paid to the design, development and production of the bracelet and its clasp as well as the quality control tests they go through.

18 – THE CARATAGE OF THE GOLD USED TO MANUFACTURE THE HOUR MARKERS
The hour markers on the unique lavender dial of the Lady-Datejust 28 are fashioned from 18 ct gold to prevent tarnishing. On each hour marker is a diamond that is set by hand except that of 12 o’clock, which features the Rolex crown logo. Handiwork features prominently in a Rolex dial as many components are designed and manufactured in-house by hand to ensure a high level of perfection.

2236 — THE REFERENCE NUMBER OF THE CALIBRE FITTED IN THE LADY-DATEJUST 28
As with all Rolex watches, the timepiece is not just a pretty face. The Lady-Datejust 28 is equipped with the self-winding calibre 2236, a new-generation mechanical movement entirely developed and manufactured in-house. What is special about this movement is the use of the Syloxi hairspring in silicon, which is insensitive to surrounding magnetic forces—many electronic products we use daily such as smartphones and laptops give strong magnetic fields that can affect the accuracy and precision of the watches. The Syloxi hairspring remains unaffected by temperature variations, and knocks and shocks—subjected to shocks, it is up to 10 times more precise than a traditional hairspring. All these contributes to calibre 2236 boasting a superlative level of chronometric performance—something that consumers greatly appreciate.
