The present Day-Date reference 18129 highlights Rolex’s innovative experimentation with precious metals during the late 20th century, specifically the introduction of "Tridor" in the mid-1980s. This striking effect is achieved by fusing white gold, pink gold and yellow gold down the central links of the bracelet, creating a seamless, multi-toned precious metal band.

This particular example stands out as an exceptionally rare and attractive configuration. It features a champagne sunburst dial set with factory diamond indexes, paired by a rare factory diamond-set bezel. The case presents a subtle two-tone contrast in yellow and white gold, perfectly complemented by the iconic Tridor President bracelet. Offered in attractive overall condition, this reference 18129 is complete with its original presentation box and punched guarantee originating from Hong Kong.

Rolex

Swiss | 1905

Founded 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.
