In 1848, Louis Brandt, the descendant of a watch making family and a resident of the Swiss clock-making center of La Chaux-de-Fonds, started assembling pocket watches out of parts from local clockmakers. By 1889, Louis Brandt & Fils, the precursor to Omega, was the largest watch manufacturer in Switzerland, producing more than 100,000 watches annually.

The first Omega wristwatch — in fact, it was one of the first industrially made wristwatches in the world — appeared in 1900. It had a silver double-hinged case, fixed attachments for a bracelet-strap, a guilloché back, enamel dial, Arabic hour numerals, and pear-shaped hands. This was followed in 1902 with a men’s wristwatch for watch maker Edwin J. Vokes of Bath and the Kirby Beard department store in Paris. A women’s version of the watch appeared in 1910.

During World War I, Omega made wristwatches for British Royal Flying Corps and communications troops in the U.S. Army. These military wristwatches had a white enamel dial, Arabic numerals, radium skeleton hands, and either a chrome-plated metal or silver case. Some versions featured a tempered-steel grid over the watch face to protect it from shocks.

Omega created a shock of its own in 1925 when it introduced its Ladies’ Jewelry Watch at the Paris Decorative Arts Exhibition. This fashion-forward timepiece had a rectangular platinum case, which, along with the bracelet, was set with a large sapphire and 82 diamonds.

The 1940s were a very busy time for Omega. In addition to making watches for the military during World War II, Omega introduced its Chronomètre in 1942. This handsome, highly accurate wristwatch had a silvered dial, Arabic numerals, and black wire hands. Best of all, its stainless-steel case was water-resistant.

After the war, in 1947, Omega produced its first calendar watch — now wearers could get the time, date, day, month, and moon phase at a glance. And in 1948, the Seamaster (based on designs created for the RAF) arrived in both chronometer and standard versions.

1952 brought the first Omega Constellation. The "connie," as vintage Constellations are known to collectors, was self-winding, had gold hour markers, and was water-resistant to 3...

The watch that would permanently cement Omega’s reputation for accuracy and reliability arrived in 1956. It was a chronograph watch called the Speedmaster. Within a decade, NASA had selected it for all of the space agency’s manned missions, but only after it withstood a battery of severe tests, including performing at zero gravity, in proximity to magnetic fields, and at temperatures ranging from -18 to +93 degrees Celsius.

The crew of Gemini 3 was the first to wear Speedmaster Professionals, as they were now known. But the watch gained its greatest acclaim on July 21, 1969 when it was strapped to the wrist of Neil Armstrong, the first man to set foot on the moon — according to his watch, the time was 02:56 GMT. Thereafter, the Speedmaster Professional was called the Moon Watch.

Omega produced a commemorative Speedmaster Professional to acknowledge this accomplishment but it did not rest on its laurels. In 1970, the Speedmaster helped rescue the Apollo 13 mission from a potential disaster — explosions had destroyed the spacecraft’s timing instruments, so astronauts and ground control alike relied on Omega wristwatches. And during the historic Apollo-Soyuz space rendezvous, Speedmaster Professionals were also worn in 1975 by American astronaut Tom Stafford and Russian cosmonaut Alexei Leonov.
