What is a chronograph movement as apposed to an automatic or quartz movement?
Typically, "Chronograph" does not describe the movement of a watch, but rather the "complication" of a watch's movement. A watch's complication is anything that provides advanced functionality, such as moon-phase display or perpetual calendar. In this case, "Chronograph" refers to a watch that is capable of stopwatch functionality in addition to timekeeping. Usually this is built into three separate dials for hours, minutes, and seconds. Such a watch can have any movement type (automatic, quartz), and can also have several complications at once. Note that digital watches with stopwatch functionality are considered "digital chronographs", and there is also the "analog-digital chronograph". Some online retailers confuse complications with the actual movement (putting "chronograph" for the movement), so further research should be done to determine whether the watch actually uses quartz or automatic movement.

Answer . movement is the displacement of an organism from one place to another.
it is the pupil
A quartz movement is the common watch movement, with the repeatingstarting and stopping action. An automatic movement represents ahigher standard of mechanical engineering.
how to keep automatic watches working in perfect condition
Automatic movement is exactly what it sounds like it would be.These are movements that are done automatically without consciousthought.
Automatic watches are self-winding ie. they need no battery and are wound by the slightest movement of the owner's wrist. Rolex invented the modern automatic back in the 1930s…. A quartz watch is powered by a battery - it keeps time by pulsing electrical current through the tiny quartz crystal, which oscillates at a predictable rate and hence keeps very accurate time. Quartz watches can have either an analog dial with the traditional hands or have a digital display - or both.
Walter G. Cady built the first quartz crystal oscillator in 1921.However, the properties of quartz making this possible were firstdiscovered by Jacques and Pierre Curie in 188…0.
it's a watch with a mechanical movement that is kept wound by the movement of the wearer's wrist as opposed to a quartz watch that needs a battery to work.
Analog movements can be either quartz or mechanical, but all digital watches have quartz movements. With respect to watches, an analog movement can be quartz or mainspring.… Analog refers principally to how the time is displayed - by the use of hands. All digital watches have quartz movements, meaning the time is kept by the counting of pulses generated by a quartz crystal at a precise frequency, and displaying the time as digits. Analog watches are mostly digital these days also, using a quartz crystal to generate pulses, counting those pulses digitally with bit counters, then electrically triggering the mechanical movement each second (or equal portion thereof). Mainspring watches are all analog. They use a mechanical clock movement driven by a mainspring to move the hands. Accuracy is determined by the period of a hairspring flywheel spinning back and forth, allowing the movement to progress a fraction of a second with each half cycle. Automatic movements use an unbalanced flywheel to wind the mainspring automatically as the watch is worn and moved on the wearer's arm.

Many analogue watches nowadays use what's called a piezo-electric crystal to generate the energy required to function. In essence a piezo-electric crystal will generate an ele…ctric current when it is deformed, which can be achieved simply by applying a force to it (such as the one generated by the movement of your arm when you're wearing the watch). Recently, Nokia patented the first self-charging mobile phone, which uses the same principles in order to charge itself.
Quartz movement means the watch is powered by a small battery that needs to be replaced on a regular basis. A good battery will normally last more than a year, and will often …last several years. The Eco-Drive watch by Citizen is powered by light. I found the following detailed description on Wikipedia: "Most Eco-Drive type watches are equipped with a special titanium lithium ion secondary battery that is charged by an amorphous silicon solar cell located behind the dial. The titanium lithium-ion composition precludes it from being affected from the regular charge/discharge cycle of other types of rechargeable batteries. Light passes through the covering crystal and dial before it reaches the solar cell. Depending on the electronic movement model, a fully charged secondary power cell could run with no further charging anywhere from 30 days to 3,175 days (8.7 years), though most Eco-Drive men's watch models offer a six-month power reserve. I've owned one of these Citizen watches for about ten years already, and it keeps excellent time while looking great on my wrist.
One can purchase an automatic chronograph from good jewellers and watch shops. There are several makes including Tag Heuer, Baume and Mercier, Omega and Tissot.
A quartz clock operates by a piece of quartz crystal. The crystal's wavelength gives off a signal which is read by a digital logic circuit. This signal is then translated into… increments of time. The digital data is converted to hours, minutes and seconds.
They are two completely different things. A movement with achronograph complication (feature) allows you to use the watch as astopwatch. A Japanese movement is simply a watch …movement designedand/or manufactured in Japan, regardless of features.
