Catalogue Essay
Explorer watches were produced to withstand the perils of alpine expeditions and the elements. The present model is a crossover between the Air King and Explorer model, evidenced by the iconic '3-6-9' numerals on the dial. Reference 5500 was fitted with either a 'Precision' or 'Super Precision' dial, as the movements were not chronometer certified. At the time, many examples were delivered to the United Kingdom.
The present watch features a well-preserved black lacquer dial that is still glossy and mirror-like in its appearance. The case furthermore retains robust proportions and crisp edges. The bracelet is stamped for the fourth quarter of 1964, attesting to the originality of this timepiece.
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.
