Notes: An early Submariner in stainless steel with a black ceramic dial. Often referred to as a 'James Bond' model. Originally this watch was sold with a 3-link stainless steel bracelet, but it is rare for one of these to survive for 60 years, so it is common to see these on eBay with replacement bands in leather.
Mechanism: 
The Oyster Perpetual began life with the calibre 1030, in 1950. This calibre was also used in several Submariner and Explorer references, 65xx and 66xx. The Cal.1030 was the most popular 18,000 bph movement at the time it was being made. It was noted for its use of a mono-metallic compensation balance and its blue steel Breguet overcoil hairspring.
Cal.1030 also features an unique rotor which is totally different with today’s, two prongs are hollowed on semi-circle, around the outer race engraved with word of “ROLEX PERPETUAL”, beneath is the word of “PATENTED” and the iconic patter of the Rolex crown.

Family Notes: The Rolex Oyster Perpetual Submariner is a line of sports watches designed for diving manufactured by Rolex, known for their resistance to water and corrosion. The first Submariner was introduced to the public in 1954 at the Basel Watch Fair. The Rolex Submariner is considered "a classic among wristwatches", manufactured by one of the most widely recognized luxury brands in the world, and due to its popularity has become the subject of massive counterfeiting. The Rolex Submariner is part of Rolex's Oyster Perpetual line. See a copy of the 1957 Submariner magazine advertisement.
The Submariner model went into production in 1953 and was showcased at the Basel Watch Fair in 1954. The assigned case reference number of this first Submariner was either 6204 or 6205. It is unclear which model came first; in any event, the two watches are nearly identical. Neither has the distinctive "cathedral" or "Mercedes" hands now so strongly associated with the Submariner line. Rather, both of these early submariners have straight "pencil" style hands. Few, if any, of the 6205 watches bear the name "Submariner" on the dial, a major distinction of modern Submariners. Some 6204 models have the Submariner logo printed below the center pinion, while others have the logo blacked out. It is believed that there were unexpected trademark issues connected with the name "Submariner" at the time the 6204 and 6205 were released, accounting for the inconsistent use of the Submariner mark on these early Submariners. Trademark irregularities notwithstanding, both the 6204 and 6205 are designated Submariner models in Rolex product literature.
