The Timeless Appeal of Yellow Rolesor
The Reference 178243 is defined by its Yellow Rolesor construction—the legendary combination of 904L Oystersteel and 18k yellow gold. This marriage of metals has been a Rolex signature since the early 1930s. In this model, the strength and reliability of the steel case are complemented by the prestige and luster of the gold bezel and center bracelet links, creating a balanced look that has remained fashionable for decades.
The Modern Domed Bezel Design
Setting the 178243 apart from more ornate versions is its smooth, domed bezel. Crafted from solid 18k yellow gold and polished to a mirror finish, the domed bezel offers a sleek, streamlined profile. This design element provides a more minimalist and modern approach to the two-tone Datejust, making it an ideal choice for those who appreciate the luxury of yellow gold without the traditional aesthetic of a fluted bezel.
Calibre 2235: A Legend in Accuracy
Reliability is a hallmark of the 178243, powered by the Perpetual Calibre 2235. This self-winding mechanical movement is a certified Swiss chronometer, a designation reserved for high-precision watches that have passed the COSC tests. Equipped with a hairspring that offers great resistance to shocks and temperature variations, the Calibre 2235 ensures that the Datejust 31 remains a dependable companion for daily wear.
The Perfect Mid-Size Proportion
At 31mm, the Reference 178243 occupies the perfect middle ground between the traditional "Lady-Datejust" and the larger "Datejust 36." This size has gained immense popularity for its contemporary presence on the wrist while maintaining an elegant silhouette. Whether configured with the sporty Oyster bracelet or the intricate five-link Jubilee bracelet, the 178243 provides a comfortable fit and a high level of versatility for any occasion.
