Breitling SA
Breitling SA () is a Swiss luxury watchmaker founded in 1884 in Saint-Imier, Switzerland, by Léon Breitling. The company is known for its precision-made chronometers designed for aviators and is based in Grenchen, Switzerland. History Breitling SA was founded in Saint-Imier by Léon Breitling in 1884. When Breitling died in 1914, the business passed to his son, Gaston, and then to his son, Willy, in 1935. Willy's children were not interested in pursuing the family business, so the Breitling factory in La Chaux de Fonds closed in December 1978. Willy, already in poor health, died in May 1979. Ernst Schneider, owner of the Sicura Company in Grenchen, bought the Breitling name from the founding family in 1979. Production of watches moved to the Sicura factory, which later changed its name to ''Montres Breitling AG'' and then ''Breitling AG'' in 1994. The Schneider family retained ownership until April 2017, when Ernst's son, Theodore Schneider, sold the majority stake (80%) i ...

Saint-Imier
Saint-Imier () is a municipality in the Jura bernois administrative district in the canton of Bern in Switzerland. It is located in the French-speaking Bernese Jura (''Jura Bernois''). The Observatoire Astronomique de Mont-Soleil is located above the village. History Saint-Imier is first mentioned in 884 as ''cella de sancti Himerii''. The municipality was formerly known by its German name ''St. Immer'', however, that name is no longer used. Its name refers to Imerius of Immertal, a 7th-century saint. According to the legend of St. Imerius, he settled in the valley as a hermit in the late 6th or early 7th century on a piece of land that bishop Marius of Lausanne gave him as a present. In 884 a ''cella'' (probably a church, farm and monastery) was mentioned on the site. Archeological excavations around the former Church of St. Martin indicate that a village grew up around the ''cella'' around the same time. Two of the 142 graves from the church have been dated to the Early ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
ETA SA
ETA SA Manufacture Horlogère Suisse (ETA SA Swiss Watch Manufacturer) designs and manufactures quartz watches and both hand-wound and automatic-winding mechanical and movements. Commonly referred to as ETA, the company is headquartered in Grenchen, Switzerland, and is a wholly owned subsidiary of The Swatch Group. Though ETA was founded by Eterna in 1856 some part of its production line can be traced back to the 1793 founding of Fabriques d’Horlogerie de Fontainemelon (FHF) by David Benguerel, Isaac Benguerel, François Humbert-Droz and Julien Humbert-Droz. Through a series of mergers, ETA has become the largest manufacturer of Swiss watch movements and controls a virtual monopoly over their production and supply. ETA has undergone several Swiss government investigations due to its market position. To resolve the concerns of Swiss government regulators, ETA has entered into an agreement that governs certain business practices. Description ETA designs and manufactures mecha ...

Aircraft Emergency Frequency
The aircraft emergency frequency (also known as GUARD) is a frequency used on the aircraft band reserved for emergency communications for aircraft in distress. The frequencies are 121.5 MHz for civilian, also known as International Air Distress (IAD) or VHF Guard, and 243.0 MHz—the second harmonic of VHF guard—for military use, also known as Military Air Distress (MAD) or UHF Guard. Earlier emergency locator transmitters (ELTs) used the guard frequencies to transmit, but an additional frequency of 406 MHz is used by a more modern emergency locator transmitter. History The choice of 121.5 MHz was made by ICAO in conjunction with ARINC and the ITU. Monitoring In the United States, the emergency frequency is monitored by most air traffic control towers, FSS services, national air traffic control centers, military air defense and other flight and emergency services, as well as by many commercial aircraft. The notice to airmen FDC 4/4386 requires "…all aircr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Civil Aviation
Civil aviation is one of two major categories of flying, representing all non-military and non-state aviation, both private and commercial. Most of the countries in the world are members of the International Civil Aviation Organization and work together to establish common Standards and Recommended Practices for civil aviation through that agency. Civil aviation includes three major categories: * Commercial air transport, including scheduled and non-scheduled passenger and cargo flights * Aerial work, in which an aircraft is used for specialized services such as agriculture, photography, surveying, search and rescue, etc. * General aviation (GA), including all other civil flights, private or commercial Although scheduled air transport is the larger operation in terms of passenger numbers, GA is larger in the number of flights (and flight hours, in the U.S.) In the U.S., GA carries 166 million passengers each year, more than any individual airline, though less than all the airl ...

Jewel Bearing
A jewel bearing is a plain bearing in which a metal spindle turns in a jewel-lined pivot hole. The hole is typically shaped like a torus and is slightly larger than the shaft diameter. The jewels are typically made from the mineral corundum, usually either synthetic sapphire or synthetic ruby. Jewel bearings are used in precision instruments where low friction, long life, and dimensional accuracy are important. Their largest use is in mechanical watches. History Jewel bearings were invented in 1704 for use in watches by Nicolas Fatio de Duillier, Peter Debaufre, and Jacob Debaufre, who received an English patent for the idea. Originally natural jewels were used, such as diamond, sapphire, ruby, and garnet. In 1902, Verneuil process, a process to make synthetic sapphire and ruby (crystalline aluminium oxide, also known as corundum) was invented by Auguste Verneuil, making jewelled bearings much cheaper. Today most jewelled bearings are synthetic ruby or sapphire. Historica ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Military Watches
A watch is a portable timepiece intended to be carried or worn by a person. It is designed to keep a consistent movement despite the motions caused by the person's activities. A wristwatch is designed to be worn around the wrist, attached by a watch strap or other type of bracelet, including metal bands, leather straps or any other kind of bracelet. A pocket watch is designed for a person to carry in a pocket, often attached to a chain. Watches were developed in the 17th century from spring-powered clocks, which appeared as early as the 14th century. During most of its history the watch was a mechanical device, driven by clockwork, powered by winding a mainspring, and keeping time with an oscillating balance wheel. These are called '' mechanical watches''. In the 1960s the electronic ''quartz watch'' was invented, which was powered by a battery and kept time with a vibrating quartz crystal. By the 1980s the quartz watch had taken over most of the market from ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hamilton Watch Company
The Hamilton Watch Company is a Swiss manufacturer of wristwatches based in Bienne, Switzerland. Founded in 1892 as an American firm, the Hamilton Watch Company ended American manufacture in 1969. Through a series of mergers and acquisitions, the Hamilton Watch Company eventually became integrated into the Swatch Group, the world's largest watch manufacturing and marketing conglomerate. Early history Hamilton succeeded three watch firms manufacturing timepieces in the same facilities in Lancaster, Pennsylvania, US, including the Lancaster Watch Company. The precursor to the Hamilton Watch Co., the Lancaster, Pennsylvania based Keystone Standard Watch Co., was started by Abram Bitner in 1886 with the purchase of Lancaster Watch Company's factory. Keystone manufactured watches featuring a patented "Dust Proof" design that used a small mica window to cover the only opening in the plate of the movement. Keystone existed until 1891 when the company was sold to Hamilton Watch ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

24 Hour Watch
Clocks and watches with a 24-hour analog dial have an hour hand that makes one complete revolution, 360°, in a day (24 hours per revolution). The more familiar 12-hour analog dial has an hour hand that makes two complete revolutions in a day (12 hours per revolution). Twenty-four-hour analog clocks and watches are used today by logistics workers, fire fighters, police officers, paramedics, nurses, pilots, scientists, and the military, and are sometimes preferred because of the unambiguous representation of a whole day at a time. Note that this definition refers to the use of a complete circular dial to represent a 24-hour day. Using the numbers from 0 to 23 (or 1 to 24) to mark the day is the '' 24-hour clock system''. Sundials use 24-hour analog dials—the shadow traces a path that repeats approximately once per day. Many sundials are marked with the double-XII or double-12 system, in which the numbers I to XII (or 1 to 12) are used twice, once for the morning hours ...

Mercury Space Program
Project Mercury was the first human spaceflight program of the United States, running from 1958 through 1963. An early highlight of the Space Race, its goal was to put a man into Earth orbit and return him safely, ideally before the Soviet Union. Taken over from the US Air Force by the newly created civilian space agency NASA, it conducted 20 uncrewed developmental flights (some using animals), and six successful flights by astronauts. The program, which took its name from Roman mythology, cost $ (adjusted for inflation). The astronauts were collectively known as the " Mercury Seven", and each spacecraft was given a name ending with a "7" by its pilot. The Space Race began with the 1957 launch of the Soviet satellite Sputnik 1. This came as a shock to the American public, and led to the creation of NASA to expedite existing US space exploration efforts, and place most of them under civilian control. After the successful launch of the Explorer 1 satellite in 1958, crew ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
