TECHNICAL CONSEPTS AND DEFINITIONS REGARDING CLOCKS, WATCHES  AND TIMING

Traditionally watches were mechanical devices. By the digital revolution in the seventies and the eighties, wholly digital watches were taking over the market because of the exactness and possibilities of functional variation that this technology offers. But soon it became clear that the old tchnology were far superior to the digital varianst regarding robustness, reliability, visibility and long durability. The producents of mechanical watches took up the fight and continued the development of the old technology in order to render the nearly the same exactness as digital watches. By now you can find watches with any degree of blending of electronic and mechanical technology. However, for high durability and reliability nothing beats a wholly mechanical watch of high quality. If durability and absolute zero failure rate is important, a wholy mechanical clock is still the choise.

High end watches often combine electronic and mechanical technology to get the best out of each one. The clock rate is typically controlled by a quarts crystal unit. The clock resceives timing signals from senders that the clock is adjusted against. Some bacic timing logic is electronic. However, the clock has mechanical arms and indicators driven by an electric motor and a mechanical clockwork.

Atomic clock: In an atomic clock a radio wave emitted form an atom is used to measure time exactly. All atoms absorb energy into their electron cloud, and emit energy again from their electron cloud in the shape of very short radio waves or light. These waves have only specific frequencies. Elements used in atomic clocks are cesium, rubidium and hydrogen.

The most common techology has a chamber with a gas containing the absorbing or emitting atoms. Then there is an electric oscilating circuit feeding to a micro wave emitter. The radio waves are fed into the chamber. This will cause the atoms in the chamber to absorb energy from the micro waves and emit that energy againg with their own specific frequencies. The intensity of the emitted micro waves from the chamber is measured at the same time as the frequency of the oscilating circuit is gradually tuned. When the microwaves emitted from the chamber is at its maximum, the frequency of the oscilating circuit is exactly the same as that of the emitted radiowaves. When this is achieved, the clock is tuned in, and the oscilations of the circuit is then used to feed a counter.

Up to now, atomic clocks have been bulky devices only suitable for use in laboratories. However, by now atomic clock chips have been made, and those will certainly appear in watches and other small clocks. The standard time of the world is based on a number of atomic clocks on different geografical locations, and that are syncronized against each other. The timing information from these clocks are transmitted to the whole world through a set of radio senders. In the international timing standards, radio wave frequencies from the element caesium is used. The exact definition of second is based on a radio frequency from this element.

Radio clock watches are often erronously called atomic watches.

Atomic clock sync (synchronization): Resceiving data about exact time from dedicated senders around the world. These time data are based on a few atomic clocks situated at different geographical locations and synchronized with each other. A radio clock is automatically adjusted from such signals. You can also get software to you PC that fetches time data based on the world's standard atomic clocks.

Automatic mechanical watches: Automatic watches use a fairly heavy-weighted rotor that will turn around because of its weight when the arm of the wearer moves, and this rotating movement will wind up the spring. 

Chronometer: A chronometer is any clock with negible distortions of the time indicated as long as the real time passes. Traditionally a clock with such an exactness that it could be used for navigational purposes at sea was called a chronometer. An exact enough watch is by this definition a chronometer. Traditionally clocks with a chronometer quality were used on ships and in aeroplanes for navigational purposes, and in laboratories.

Electronic watch: This is a watch where all the technology is electronic as timing impulse unit, timing logics and indicator system. However, in high end modern watches electronic and mechanical components are typically combined to get the best out of each technology.

Hybrid watches: In high end modern watches electronic and mechanical components are typically combined to get the best out of each technology.

Incablock: This is a system for protection of the mechanics of a watch against external impact. The stones and the pivots of sprockets and other rotating parts are monted in bearings with a spring mechanism capable of absorbing shock. When a mechanical shock occurs, the pivots and stones are pushed out of position, but agaist the resistance of the spring. During that movement the energy of the shock is absorbed. When the shock is over, the spring pćushes the pivot and the stones back in position again.

Manual mechanical watches: In these watches on winds the spring by turning a crown.

Quarts clock: In a quarts clock, a vibrating quarts crystal is used to control the speed of a clock. A quarts crystal lattice vibrates mechanically with a very high frequency if set in vibration. The distribution of electric charges within the chrystal is such that the mechanical vibration also creates an electric occilation in the chrystal. In a quarts clock, a quarts crystal is a part of an alternating current circuit, and in such a way that the frequency of the crystal occilations determines the current frequency.

The curcuit is also connected to other curcuits that transmit the occilations down to occilations of lower freequency. Ultimately through these circuits a mechanical pendulum is set in motion that drives the clock with a frequency that is a whole fraction of the quarts frequency, or the circuits are used to count up a digital counter. Many watches are quarts clocks or they use another type of mineralic crystal with the same function.

Mechanical watch: In a mechanical watch all the technical parts are made from moving mechanics. Generally a high quality mechanical watch is more robust, will last longer and is more reliable than an electronic watch.

Pendulum: The pendulum is controlling the speed of a clock. Mechanical watches have a pendulum combined with a spring. The pendulum typically has the shape of an occilating wheel. The energy source of the clock is connected to the pendulum and is keeping it swinging. This is done by giving the pendulum a push each time it is at one of the extremes of the swing. The pendulum is swinging with a constant rate. The pendulum transmits the energy further to the timing mechanics. For each swing, the pendulum pulls a gear foreward only one step. Thus the rate of the clock is controlled.

An electronic clock does not have a mechanic pendulum but it has something analogous. Typically it has a piezoelectric crystal, for example made of quartz. Such a crystal will be set in very rapid mechanical undulation of a constant frequency when subjected to osciliating electric fields with that frequency typical for the crystal. If the crystal allready is mechanically swinging, it will cause eletric fields that are swinging with the same frequency. The reason for this is that the electrons around the atoms in the crystal are not evenly distributed. A curcuit is set up such that the crystal will be subjected to a field in one specific direction when the structure of the crystal swings in one direction, and so that the current in the circuit is swiched to the other direction when the crystal swings back.  Then the circuit will get current that go back and forth with the same frequency that the crystal swings. This frequency of the current is then used to path the timing logic.

Radio clock or watch (often wrongly called atomic watch): A radio clock has electronic equipment that resceives radio signals from dedicated senders giving the exact time that the clock thereafter adjusts itself after. There are a few primary atomic clocks around the world that serves as prototypes for the time measurements in the whole world. These primary clocks are constantly synchronized against each other. These primary clocks transmit time signals to radio senders owned by different goverments or companies. A radio clock resceives signals from these senders.

Second - international standard definition: The second is currently defined as the duration of 9,192,631,770 periods of the radiation caused by the transition between the two hyperfine levels of the ground state of the caesium-133 atom.  The trasition must take place at a temperature of 0 K (absolute zero) and at zero magnetic field. The second thus defined is equivalent to the ephemeris second. The international standard symbol for a second is s (see ISO 31-1).

Stones or jewels: Hard smooth stones are used at the placed where sprockets, pivots or other rotating or moving parts inside the watch are suspended in order to reduce friction, to increase the exactness of the watch and to make the watch more durable. The function of the stones is comparable to that of bearings in larger mechanical equipment. Typically small rubine, safirs or other corundum stones are used because of the hardness of this mineral.

Tourbillon: A tourbillon is a mechanical device that counteracts variations of a clock's rate because of an variating gravitational friction within the mechanics of the clock. The weight of the mechanical parts within the clock creates friction, and this friction will to some degree determine the speed of a watch. But since the watch is not held constantly at the same position, this friction will be unpredictable, and it is therefore impossible to regulate the speed of the watch exactly.

A tourbillon is a rotating inner case that contains the mechanics of the watch. The rotation will make the averidge friction within the mechanics during a given time period constant, and the indicated time vill be less distorted from real time as the real time passes. By now there are other methods of giving exactness, so a tourbillon is not necessary any more. Watcing a rotating tourbillon is however entertaining. Fine watches are therefore sometimes made in such a way that the mechanics includes a tourbillon, and the mechanics is visible through a glass surface, so that the rotating tourbillon can be seen. By makeing the tourbillon rotating one round per minute, it also cam be used as a second pointer.
