Telemeter 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 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 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, diving and submarine maneuvering. Since the 1980s, the term ''chronograph'' has also been applied to all digital watches that incorporate a stopwatch function. History The term ''chronograph'' comes from the G ...

Automatic Watch
An automatic watch, also known as a self-winding watch or simply an automatic, is a mechanical watch where the natural motion of the wearer provides energy to wind the mainspring, making manual winding unnecessary if worn enough. It is distinguished from a ''manual watch'' in that a manual watch must have its mainspring wound by hand at regular intervals. Operation In a mechanical watch the watch's gears are turned by a spiral spring called a mainspring. In a ''manual watch'' energy is stored in the mainspring by turning a knob, the ''crown'' on the side of the watch. Then the energy from the mainspring powers the watch movement until it runs down, requiring the spring to be wound again. A self-winding watch movement has a mechanism which winds the mainspring using the natural motions of the wearer's body. The watch contains an oscillating weight that turns on a pivot. The normal movements of the watch in the user's pocket (for a pocketwatch) or on the user's arm (for a wristwat ... [...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 ...

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 ...

TAG Heuer Monaco
The TAG Heuer Monaco (originally Heuer Monaco) is a series of automatic chronograph wristwatches originally introduced by Heuer in 1969 in honour of the Monaco Grand Prix. The Monaco was revolutionary for being the first automatic square cased chronograph (Rolex was the first with a square chronograph in 1940; https://le-monde-edmond.com/pak-a-rolex/). The Hollywood film star Steve McQueen used the watch to accessorize his character in the 1971 film ''Le Mans''. In the decades after his death the use of film stills has made the watch synonymous with McQueen. Although it was discontinued in the mid-1970s, the Monaco was reissued with a new design in 1998 and was reintroduced again with an entirely new mechanisms in 2003 in response to McQueen's increasing popularity. Design The watch typically features a pair of pushbuttons at the 2 and 4 o’clock position. The dials for the minute and hour counters are at 9 and 3 o'clock respectively. There is a hand-applied date window at 6 o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tachymeter (watch)
A tachymeter (pronounced ) is a scale sometimes inscribed around the rim of an analog watch with a chronograph. It can be used to conveniently compute the frequency in hours of an event of a known second-defined period, such as speed (distance over hours) based on travel time (distance over speed), or measure distance based on speed. The spacings between the marks on the tachymeter dial are therefore proportional to , where ''t'' is the elapsed time. The function performed by a tachymeter is independent of the unit of distance (e.g. statute miles, nautical miles, kilometres, metres etc.) as long as the same unit of length is used for all calculations. It can also be used to measure the frequency of any regular event in occurrences per hour, such as the units output by an industrial process. A tachymeter is simply a means of converting ''elapsed time'' (in seconds per unit) to ''rate'' (in units per hour). Measuring speed To use a tachymeter-equipped watch for measuring speed, ...
