Speedmaster
Omega Speedmaster is a line of chronograph wristwatches produced by Omega SA. While chronographs have existed since the late 1800s, Omega first introduced this line of chronographs in 1957. Since then, many different chronograph movements have been marketed under the Speedmaster name. Astronaut Walter Schirra was the first person to wear one in space in 1962 during his Mercury-Atlas 8 mission. The manual winding Speedmaster Professional or "Moonwatch" is the best-known and longest-produced; it was worn during the first American spacewalk as part of NASA's Gemini 4 mission, and was the first watch worn by an astronaut walking on the Moon during the Apollo 11 mission. The Speedmaster Professional remains one of several watches qualified by NASA for spaceflight, and is still the only one so qualified for EVA. The Speedmaster line also includes other models, including analog-digital and automatic mechanical watches. Early development The Speedmaster was not originally designed fo ...

Omega SA
Omega SA is a Swiss luxury watchmaker based in Biel/Bienne, Switzerland. Founded by Louis Brandt in La Chaux-de-Fonds in 1848, the company formerly operated as ''Louis Brandt et Fils'' until incorporating the name ''Omega'' in 1903, becoming ''Louis Brandt et Frère-Omega Watch & Co.'' In 1984, the company officially changed its name to ''Omega SA'' and opened its museum in Biel/Bienne to the public. Omega is a subsidiary of the Swatch Group. Britain's Royal Flying Corps used Omega watches in 1917 for its combat units, followed by the U.S. Army in 1918, and NASA in 1969 for Apollo 11. The Omega Speedmaster, Omega Speedmaster Moonwatch is marketed as the first watch worn on the Moon, becoming one of the watchmaker's most iconic models. Omega is the current official timekeeper of the Olympic Games, Olympics, having first done so in 1932 Summer Olympics, 1932, in addition to being the timekeeper of the America's Cup yacht race.

Watch
A watch is a timepiece carried or worn by a person. It is designed to maintain a consistent movement despite the motions caused by the person's activities. A wristwatch is worn around the wrist, attached by a watch strap or another type of bracelet, including metal bands or leather straps. A pocket watch is carried in a pocket, often attached to a chain. A stopwatch is a type of watch that measures intervals of time. During most of their history, beginning in the 16th century, watches were mechanical devices, driven by clockwork, powered by winding a mainspring, and keeping time with an oscillating balance wheel. These are known as '' mechanical watches''. In the 1960s the electronic ''quartz watch'' was invented, powered by a battery and keeping time with a vibrating quartz crystal. By the 1980s it had taken over most of the watch market, in what became known as the quartz revolution (or the quartz crisis in Switzerland, whose renowned watch industry it decima ...

Chronographs
A chronograph is a specific type of watch that is used as a stopwatch combined with a display watch. A basic chronograph has hour and minute hands on the main dial to tell the time, a small seconds hand to tell that the watch is running, and a seconds hand on the main dial usually equipped with a sweeping movement for precision accompanied by a minutes sub dial for the stopwatch. Another sub dial to measure the hours of the stopwatch may also be included on a chronograph. The stopwatch can be started, stopped, and reset to zero at any time by the user by operating pushers usually placed adjacent to the crown. More complex chronographs often use additional complications and can have multiple sub-dials to measure more aspects of the stopwatch such as fractions of a second as well as other helpful things such as the moon phase and the local 24-hour time. In addition, many modern chronographs include tachymeters on the bezels for rapid calculations of speed or distance. Louis M ...

Société Suisse Pour L'Industrie Horlogère
Société Suisse pour l'Industrie Horlogère (SSIH) is a former group of Swiss watchmakers comprising the brands Omega, Tissot and Lemania. History SSIH was created on February 24, 1930 in Geneva by Tissot and Omega, to be joined in 1932 by Lemania Watch Co and A. Lugrin Co in L'Orient ( Vallée de Joux). The company specialized in the manufacture of horological complications, enabling Omega to obtain the timing of the 1932 Olympic Games in Los Angeles. This was an important step for the development of Omega's important Sports' Watches segment with exclusive chronographs, such as the Omega Speedmaster. The merger agreement foresaw Omega's concentration on the luxury watch segment, whereas Tissot's mission was to concentrate on the medium price range segment. In 1983, SSIH and the Allgemeine Gesellschaft der schweizerischen Uhrenindustrie AG (ASUAG) the other most important Swiss Watch Group, were forced by their Swiss Banks to merge into a new holding company named Soc ...

Gemini 4
Gemini 4 (officially Gemini IV) With Gemini IV, NASA changed to Roman numerals for Gemini mission designations. was the second crewed spaceflight in NASA's Project Gemini, occurring in June 1965. It was the tenth crewed American spaceflight (including two X-15 flights at altitudes exceeding ). Astronauts James McDivitt and Ed White (astronaut), Ed White orbited the Earth 66 times in four days, making it the first US flight to approach the five-day flight of the Soviet Union, Soviet Vostok 5. The highlight of the mission was the first space walk by an American, during which White floated free outside the spacecraft, tethered to it, for approximately 23 minutes. The flight also included the first attempt to make a space rendezvous as McDivitt attempted to maneuver his craft close to the Titan II GLV, Titan II upper stage which launched it into orbit, but this was not successful. The flight was the first American flight to perform many scientific experiments in space, including us ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Omega Seamaster
The Omega Seamaster is a line of automatic winding mechanical diving watches from Omega with a history that can be traced back to the original water-resistant dress-style watch released in 1948. The Seamaster collection is perhaps best known today for the Seamaster Diver Professional 300m model that has been worn in the James Bond movie franchise since 1995. Originally conceived as a dressy, water-resistant timepiece, the Omega Seamaster has evolved to a robust sports watch line, typically with a stainless steel case, robust water resistance, and an official chronometer-certified movement within. The Diver Professional 300m is most famous for its "train-track" five link steel bracelet, its helium release valve at the 10:00 position, the wave pattern dial on certain model generations, and the skeletonized handset. The current model range is split into separate lines of Seamaster models: the Aqua Terra line serves as the everyday sports watch model, the Diver Professional 300m ...

Lemania
Lemania was a Swiss watch manufacturer and manufacturer of watch movements. It was founded in 1884 by Alfred Lugrin (1858-1920), who had trained at Jaeger-LeCoultre. Lugrin received awards and gold medals at exhibitions in Milan in 1906 and in Bern in 1914. Until 1930, the factory was called Lugrin SA, until Lugrin's son-in-law Marius Meylan established the firm Lemania Watch Co., based in L'Orient, Switzerland (Vaud). In 1932, Lemania, Omega and Tissot merged to form the SSIH group. Lemania produced movements for Omega, including for the Speedmaster that Buzz Aldrin wore on the moon. With the advent of electronic watches in the 1970s, sales of mechanical watches from the SSIH Group collapsed. In 1980, creditor banks gave Nicolas Hayek the task of restructuring Restructuring or Reframing is the corporate management term for the act of reorganizing the legal, ownership, operational, or other structures of a company for the purpose of making it more profitable, or better ...

Poly(methyl Methacrylate)
Poly(methyl methacrylate) (PMMA) is a synthetic polymer derived from methyl methacrylate. It is a transparent thermoplastic, used as an engineering plastic. PMMA is also known as acrylic, acrylic glass, as well as by the trade names and brands Crylux, Walcast, Hesalite, Plexiglas, Acrylite, Lucite, PerClax, and Perspex, among several others ( see below). This plastic is often used in sheet form as a lightweight or shatter-resistant alternative to glass. It can also be used as a casting resin, in inks and coatings, and for many other purposes. It is often technically classified as a type of glass, in that it is a non-crystalline vitreous substance—hence its occasional historic designation as ''acrylic glass''. History The first acrylic acid was created in 1843. Methacrylic acid, derived from acrylic acid, was formulated in 1865. The reaction between methacrylic acid and methanol results in the ester methyl methacrylate. It was developed in 1928 in several different la ...

Test Pilots
A test pilot is an aircraft pilot with additional training to fly and evaluate experimental, newly produced and modified aircraft with specific maneuvers, known as flight test techniques.Stinton, Darrol. ''Flying Qualities and Flight Testing of the Airplane.'' American Institute of Aeronautics and Astronautics, Inc., 1996, p. 265 History Test flying as a systematic activity started during the First World War, at the Royal Aircraft Establishment (RAE) in the United Kingdom. An "Experimental Flight" was formed at the Central Flying School. During the 1920s, test flying was further developed by the RAE in the UK, and by the National Advisory Committee for Aeronautics (NACA) in the United States. In the 1950s, NACA was transformed into the National Aeronautics and Space Administration, or NASA. During these years, as work was done into aircraft stability and handling qualities, test flying evolved towards a more qualitative scientific profession. In the 1950s, test pilots were ...
