Jim Morrison dies in Paris at age 27

1971 Omega Seamaster 176.0001 Automatic Chronograph.

Made in 5 dial/cases configuration:

They equipped Omega Seamaster 176.0001 with the cal. 1040, the first Omega automatic Chronograph. With large center chronograph seconds and minutes hands. 12 hour counter at 6 o’clock, continues small seconds hand, 24-hour indicator at 9 o’clock and date.

Raoul-Henri Eraddeveloped and Lemaniaproduced it; Noteworthy to mention that a ball-bearings mounts its rotor.

Although an early automatic chronograph, the caliber 1040 was not the first automatic chronograph in the world. it was preceded by the Chrono-Matic and the el Primero which were the first commercial automatic Chrono calibers.


Albert Piguet, Lemania’s chronograph specialist, had already made an automatic Chronograph prototype in 46, but unfortunately, Paul-Emile Brandt, shelved this revolutionary project at the time considering it superfluous.

Launched in 1948 to coincide with the brand’s 100th anniversary, the Omega Seamaster line is the oldest in the current collection.

Loosely based on the waterproof wristwatches made for the British military at the end of World War II, the Seamaster first intended as a robust yet elegant watch for active individuals who wanted a watch for the town, sea and country.

The Seamaster achieved first diving-record in 1955, when diver Gordon McLean reached a depth of 62.5 meters in Australia.

The key to these watches was the O-ring rubber gasket. At this time, water-resistant watches generally used lead or shellac gaskets. Which were susceptible to temperature changes. The engineers at OMEGA were so sure of the Seamaster that one flew the Polar Route over the North Atlantic attached to the outside of a Douglas DC6 aircraft in 1956.

I consider the Seamaster two lines in one: the big, heavy Professional, designed for divers for deep diving, and a dress range also made by Seamaster.

Louis Brandt founded Omega in 1848 at the age of 23. The brand’s reputation grew fast and in 1895 the watches achieved a precision of 30 seconds a day. By the turn of the 19th century, one of Switzerland’s largest watch companies with 240,000 watches, Omega produced annually and employing 800 people.

Omega made its debut in sports during the Gordon Bennett international ballooning Cup in 1917; since then Omega has gone on to be the official timekeeper at 21 Olympic Games.

In 1936 Omega set the remarkable World precision record of 97.8 points at the Kew-Teddington observatory in England.

In 1957, with Motorsport in mind, Omega launched the Speedmaster, which in 1965 NASA chose as its official chronometer in Space. Four years later the Moonwatch was the first watch to be worn on the Moon. When on 21st July 1969 Neil Armstrong made his giant leap for mankind.Currently Omega belongs to the Swatch Group.
