Produced until 1980, the ref. 1675 was in production for over 21 years, with a total of 9 marks inclusive of Mark 0 and service marks. The very first examples of the GMT-Master ref. 1675 were fitted with either a gilt chapter ring dial or gilt non-chapter ring dial. After the gilt era of the reference, the matte dial was born first with Mark 0.
The present example is a Rolex GMT-Master Mark I. This is confirmed by the long “E” in the Rolex signature on the dial as well as the corresponding 2.4 million serial number, which fits into the 1.9 million to 2.9 million range for Mark I examples.
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.
