It is no exaggeration to claim that the Rolex Submariner is the most famous watch model in the world. The first examples of this iconic diver's watch were produced in 1953 and made their official debut at the Basel Fair in 1954. The initial references of the Submariner were 6204, 6205, and 6200. While references 6204 and 6205 offered water resistance down to 100 meters, the more robust 6200 was designed for professional divers and was water-resistant down to 200 meters.

For many collectors, reference 6200 is considered a "The holy grail" of Submariner collecting and is also referred to as "King Sub". All watches that have appeared on the market have serial numbers between 31,9xx and 32,2xx. Therefore, the total production of 6200 is estimated to be around 300 pieces, of which only a small number have surfaced on the secondary market.

The model 6200 has distinctive features that make it particularly interesting. It was the first model to have what is known as a "Big Crown," referring to the 8 mm "Brevet" crown. Additionally, the 6200 was the first model to feature a dial with a so-called "3-6-9" or "Explorer" layout.
