Catalogue Essay
The present Rolex Day-Date reference 18238, dating from circa 1990, features an exceptionally rare blue aventurine dial adorned with diamond-set indexes. Aventurine, a type of quartz, is known for its translucency and the platy mineral inclusions that give the dial a stunning resemblance to a starry night sky. Blue aventurine dials are incredibly scarce, with only a handful of examples ever appearing at auction. Hardstone dials from Rolex have always captivated enthusiasts due to their vibrant colors, unique textures and rarity, requiring meticulous precision and dedication to craft such mesmerizing dials.
This present watch boasts a case with clean, sharp edges and a dial that shows no cracks or fissures. Furthermore, it is accompanied by its guarantee and presentation box, enhancing its collectability.
Rolex
Swiss | 1905Founded in 1905 England by Hans Wilsdorf and Alfred Davis as Wilsdorf & Davis, it soon became known as the Rolex Watch Company in 1915, moving its headquarters to Geneva in 1919. Like no other company, the success of the wristwatch can be attributed to many of Rolex's innovations that made them one of the most respected and well-known of all luxury brands. These innovations include their famous "Oyster" case — the world's first water resistant and dustproof watch case, invented in 1926 — and their "Perpetual" — the first reliable self-winding movement for wristwatches launched in 1933. They would form the foundation for Rolex's Datejust and Day-Date, respectively introduced in 1945 and 1956, but also importantly for their sports watches, such as the Explorer, Submariner and GMT-Master launched in the mid-1950s.
One of its most famous models is the Cosmograph Daytona. Launched in 1963, these chronographs are without any doubt amongst the most iconic and coveted of all collectible wristwatches. Other key collectible models include their most complicated vintage watches, including references 8171 and 6062 with triple calendar and moon phase, "Jean Claude Killy" triple date chronograph models and the Submariner, including early "big-crown" models and military-issued variants.
