1998 Omega Speedmaster Replica ref. 3894.50, cal. 861.
This watch reproduces the exact dial, hands and bezel of the first Speedmaster model launched in 1957, introduced as a sports and racing chronograph under the reference CK2915.
In 1959, a second Speedmaster version was released with alpha hands and a black aluminum bezel to improve readability. The case increased from 39mm. to 40mm. and an O-ring gasket was also added into the push buttons to improve water resistance.
The reference CK 2998 is the first Speedy that went to Space with Wally Schirra during the Mercury 8 flight in October 1962.
In 1962 Omega introduced the Speedmaster’s typical straight baton hands and next year the first 42mm, asymmetrical case, adding protection to the chronograph pushers and crown, which is basically the same case in production today.
The Professional marking appeared below the Speedmaster logo in 1966 after being approved by NASA.
In 1968, Omega decided to replace the movement cal. 321 with a movement more accurate and cheaper to produce, the cal. 861, also produced by Lemania.
To celebrate the moon landing, the case back of the Speedmaster Professional changed in 1969. The engraved Hippocampus was removed and the phrases “The first watch worn on the Moon” and “Flight qualified by NASA for all manned space missions” were engraved. This was changed for the last time in 1971 to incorporate the Hippocampus on the back as well. This case back design is still being used today on the Speedmaster Professional.
Omega was founded in 1848 by Louis Brandt 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 Omega was one of Switzerland’s largest watch companies with 240,000 watches 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 was chosen by NASA 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.
