Flyback Chronograph
A flyback chronograph is a watch complication, in which the user can use the reset function without the need to first stop the chronograph. In regular chronographs, the user must stop, reset, and restart the chronograph in order to time an event after the chronograph has started. Other names The flyback function is also known by some other names: * Retour-en-vol (french: retour - to return; en - on; vol - flight) * Taylor system * Permanent zero setting Overview The flyback function is a complication inspired by everyday life, as are some other complications: world time, universal time, power reserve. Most flyback chronographs are constructed with the usual crown at 3 o'clock and 2 push-pieces at 2 and 4 o'clock. Usually the flyback function is controlled by the push-piece at 4 o'clock whereas the one at 2 o'clock is used to stop the chronograph. Many chronographs are equipped with the flyback function, especially watches meant for pilots. It is much easier from the point of ...

Seiko Flyback-Automatic-Chronograph Cal
, commonly known as Seiko ( , ), is a Japanese maker of watches, clocks, electronic devices, semiconductors, jewelry, and optical products. Founded in 1881 by Kintarō Hattori in Tokyo, Seiko introduced one of the first quartz watches and the first quartz watch with a chronograph complication. Seiko was a wristwatch manufacturer for Japanese soldiers during World War II. History 1881 founding to 1929 In 1881, Seiko founder Kintarō Hattori opened a watch and jewelry shop called "K. Hattori" () in Tokyo. Kintarō Hattori had been working as clockmaker apprentice since the age of 13, with multiple stints in different watch shops, such as “Kobayashi Clock Shop”, ran by an expert technician named Seijiro Sakurai; “Kameda Clock Shop” in Nihonbashi; and “Sakata Clock Shop” in Ueno, where he learned how to both sell and repair timepieces. Around the time of Seiko's founding, watchmakers in Tokyo, Osaka, and Nagoya were studying and producing pocket watches based on Wes ...

Watch
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 the mechani ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Complication (horology)
In horology, a complication is any feature of a mechanical timepiece beyond the display of hours, minutes and seconds. A timepiece indicating only hours, minutes and seconds is known as a simple movement. Common complications include date or day-of-the-week indicators, alarms, chronographs (stopwatches), and automatic winding mechanisms. Complications may be found in any mechanical clock, but they are most notable in mechanical watches where the small size makes them difficult to design and assemble. A typical date-display chronograph may have up to 250 parts, while a particularly complex watch may have a thousand or more parts. Watches with several complications are referred to as ''grandes complications.'' Types Timing (visible) * Chronograph, with a second hand that can be stopped and started to function as a stopwatch. ** Double chronograph or ''rattrapante'', multiple second hands for split-second, lap timing or timing multiple events ** Flyback chronograph, allowing ...

Chronograph
A chronograph is a specific type of watch that is used as a stopwatch combined with a display watch. A basic chronograph has an independent sweep second hand and a minute sub-dial; it can be started, stopped, and returned to zero by successive pressure on the stem. More complex chronographs use additional Complication (horology), complications and can have multiple sub-dials to measure seconds, minutes, hours and even fractions of a second. In addition, many modern chronographs use moveable bezels as Tachymeter (watch), tachymeters for rapid calculations of speed or distance. Louis Moinet invented the chronograph in 1816 for use in tracking astronomical objects. Chronographs were also used heavily in artillery fire in the mid to late 1800s. More modern uses of chronographs involve aircraft piloting, auto racing, Underwater diving, diving and submarine maneuvering. Since the 1980s, the term ''chronograph'' has also been applied to all Watch#Digital, digital watches that incorpor ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
World Time
A time zone is an area which observes a uniform standard time for legal, commercial and social purposes. Time zones tend to follow the boundaries between countries and their subdivisions instead of strictly following longitude, because it is convenient for areas in frequent communication to keep the same time. All time zones are defined as offsets from Coordinated Universal Time (UTC), ranging from UTC−12:00 to UTC+14:00. The offsets are usually a whole number of hours, but a few zones are offset by an additional 30 or 45 minutes, such as in India, South Australia and Nepal. Some areas of higher latitude use daylight saving time for about half of the year, typically by adding one hour to local time during spring and summer. List of UTC offsets In the table below, the locations that use daylight saving time (DST) are listed in their UTC offset when DST is ''not'' in effect. When DST is in effect, approximately during spring and summer, their UTC offset is increas ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Universal Time
Universal Time (UT or UT1) is a time standard based on Earth's rotation. While originally it was mean solar time at 0° longitude, precise measurements of the Sun are difficult. Therefore, UT1 is computed from a measure of the Earth's angle with respect to the International Celestial Reference Frame (ICRF), called the Earth Rotation Angle (ERA, which serves as a modern replacement for Greenwich Mean Sidereal Time). UT1 is the same everywhere on Earth. UT1 is required to follow the relationship :ERA = 2π(0.7790572732640 + 1.00273781191135448'' · Tu'') radians where ''Tu'' = ( Julian UT1 date - 2451545.0). History Prior to the introduction of standard time, each municipality throughout the clock-using world set its official clock, if it had one, according to the local position of the Sun (see solar time). This served adequately until the introduction of rail travel in Britain, which made it possible to travel fast enough over long distances to require continuous ...

Power Reserve
A power reserve indicator (originally called ) is a complication of the watch, which is designed to show the amount of remaining stored energy. The power reserve indicator indicates the tension on the mainspring at any particular moment. Overview The power reserve indicator is one of the most useful features of a mechanical watch besides the actual time display. A mechanical watch is operated by either automatic or manual winding. In order to run at a regular rate a mechanical timepiece needs to have at least 30 per cent of its mainspring wound. An automatic timepiece needs to be worn for about 10–15 hours before it is fully wound. The power reserve indicator displayed on the watch with automatic- winding movement shows how long a watch will function when not worn. On a manual winding watch, it shows the time left until the watch needs winding. Brief history There are numerous devices for recording the amount of mainspring power stored in the barrel. Power reserve indicator ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Push-button
A push-button (also spelled pushbutton) or simply button is a simple switch mechanism to control some aspect of a machine or a process. Buttons are typically made out of hard material, usually plastic or metal. The surface is usually flat or shaped to accommodate the human finger or hand, so as to be easily depressed or pushed. Buttons are most often biased switches, although many un-biased buttons (due to their physical nature) still require a spring to return to their un-pushed state. Terms for the "pushing" of a button include pressing, depressing, mashing, slapping, hitting, and punching. Uses The "push-button" has been utilized in calculators, push-button telephones, kitchen appliances, and various other mechanical and electronic devices, home and commercial. In industrial and commercial applications, push buttons can be connected together by a mechanical linkage so that the act of pushing one button causes the other button to be released. In this way, a stop button ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...

Longines
Compagnie des Montres Longines, Francillon S.A., or simply Longines (), is a Swiss luxury watchmaker based in Saint-Imier, Switzerland. Founded by Auguste Agassiz in 1832, the company has been a subsidiary of the Swiss Swatch Group and its predecessors since 1983. Its winged hourglass logo, registered in 1889, is the oldest unchanged active trademark registered with WIPO. History 1832–1867 Longines was founded in Saint-Imier in 1832 by Auguste Agassiz, a Swiss watchmaker and brother of biologist Louis Agassiz. Auguste had two partners, lawyers Henri Raiguel and Florian Morel; the company's original name was ''Raiguel Jeune & Cie''. By 1846, Raigeul and Morel had retired from the watch industry, leaving Agassiz as sole company head. Several years later, Agassiz brought in his bright, enterprising nephew, trained economist Ernest Francillon, into the business. Francillon was the mastermind behind several impressive innovations that would distinguish the company from its compet ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Double Chronograph
Double chronograph is a watch that includes two distinct stopwatch mechanisms in order to measure two separate events concurrently and/or comparatively. It is often confused with the flyback chronograph. Other names * Rattrapante chronograph (french: rattraper - the act of recovering, recapturing) * Split-second chronograph * Split chronograph Functioning A watch with a double chronograph has two seconds hands. One hand is superimposed over the other. While one hand moves continuously, the other one can be either stopped, started or reset to zero. The first push releases both hands. While one continues registering the time, the other hand can be repeatedly stopped. In order to stop and bring both hands to zero a watch has a return pusher. The position of the pusher, controlling the split-seconds function is usually at either 10 or 8 o'clock. Brief history The double chronograph was previously called Fly-back second, but nowadays 'Fly-back second' relates to a chronograph wher ...
