Background to the Zenith El Primero Sub-Sea watch: The Zenith El Primero Sub-Sea range of watches started in 1969 and finished in 1975. Total production has been estimated at 2,500 pieces, with the diver / pilot model with tachometer representing 500 pieces. As the name implies, the Sub-Sea Diver / Pilot watch was marketed both to professional divers and pilots.
Background to Zenith: Watchmaker Georges Favre-Jacot founded the Zenith company in 1865 at the age of 22, opening a workshop in Le Locle in the canton of Neuchâtel. Zenith has a long reputation for the quality and precision of their watches. It is one of the few Swiss watch manufacturers that still produce their own movements in-house.
During World War II, Zenith were one of a group of Swiss companies, such as IWC, Longines etc given contracts by Germany to produce military watches for them. Zenith famously created the El Primero calibre, which was first released in 1969, and still produced today. This renowned movement was one of the first automatic chronograph movements and has a frequency of 36,000 alternations per hour (5 Hz). This high rate allows a resolution of 1⁄10 of a second and a potential for greater positional accuracy over the more common standard frequency of 28,800 alternations per hour (4 Hz)
