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] |
