	The Antique Sextant - Stanley London Boxed Quartz Clock
		Note that it is not possible to mount a plaque on the inside lid because of the exposed clock movement.
		The face of the clock is protected with glass, and the quartz clock is powered by a single pen-light AA battery.
		The clock bezel measures 3 1/2 inches (9 cm) in diameter and the clock face measures 2 5/8 inches (6.7 cm) in diameter.

	Untitled Document
		The initial quartz clock was invented in 1927 by Warren A. Marrison and J.W Horton.
		Before quartz clocks, a second had been defined as 1/86,400 of an average solar day (the average amount of time it took for one rotation of the Earth).
		Nowadays, quartz clocks have advanced so much that they are found in all types of things such as calculators and computers.

	Quartz clock
		A quartz clock is an electronic oscillator that uses a quartz filter to achieve very precise frequencies.
		In modern quartz clocks, the resonator is a tuning fork shape, laser-trimmed or precision lapped to vibrate at 32,768 cycles per second.
		If a quartz wristwatch is "rated" by measuring it against an atomic clock's time broadcast, and worn on one's body to keep its temperature constant, the corrected time can easily be as accurate as 2 seconds per month, more than good enough to perform celestial navigation.

	Electric clock movement, particularly a quartz clock movement - Patent 4508458
		In an electric clock movement, the electronic components, such as an IC chip (9), a quartz crystal (10) or a diode (12), instead of being fastened to a circuit board are fastened to an extension (8) on the back plate (2).
		The present invention refers to an electric clock movement, particularly a quartz clock movement, having a gear train which is driven by an electric motor and arranged between two plates, at least one of which consists of plastic, as well as an electric circuit containing electronic components for the time-dependent driving of the motor.
		Clock movements of this type are already known in which the electronic components such as a quartz crystal, a binary divider, capacitors, resistors, diodes and transistors which together form the drive circuit for the motor are arranged on a circuit board.

	Mechanism of the Quartz Clock
		Fused quartz is often used for laboratory equipment that must not change shape as the temperature changes.
		These clocks usually have special instructions for changing the battery (the counter must not be permitted to stop), and become more accurate as they grow older.
		Quartz chronometers designed as time standards often include a crystal oven, to keep the crystal at a constant temperature.

	THE BELL SYSTEM
		Quartz crystal is the most abundant crystalline form of silicon dioxide, occurring, in some parts of the world, in large single crystals from which mechanical resonators of useful dimensions can readily be formed.
		The improvements in quartz resonators, and in their driving circuits, have resulted in the construction of quartz crystal clocks that will keep time with an accuracy better than 0.001 second a day, so that measurements of time of great interest and value to astronomers and geophysicists can now be made with an accuracy hitherto unattainable.
		The quartz resonators used in these installations are believed to be similar to those in Clocks III and IV in the Physikalisch-Technische Reichsanstalt installation except that some of them were made for 100 kilocycles instead of the original 60 kilocycles.

		For longer life in hard to reach places or where the clock is used in unusually cold/warm environments, battery life can be extended by using a lithium battery.
		The clock has had a loss of power or has just been started up and is searching for a signal.
		This is normal, and the clock will set itself to the correct time after it receives a signal.

	Automotive Clock Update - Quartz for your Car Clock
		The early self-winding clocks have two points, similar to ignition points, that get closer and closer as the clock ticks.
		The new clock is considerably lighter than the factory unit but it is identical to the original.
		The new clock has two plastic gears that need to be installed with the old metal ones.

		The size that you use is determined by the size of the clock dial or fare that you use.
		If you decide to use a quartz movement with separate hands and dial, it is much easier to create a design that is truly unique.
		While it may be possible to use one of our movements to repair your clock, we have no way of telling because we can not reference the brand and model number of your clock to determine what you may need.

	Quartz clock - Wikipedia, the free encyclopedia
		A quartz clock is a clock that uses an electronic oscillator which is made up by a quartz crystal to keep precise time.
		Since the introduction of the low current consumption microprocessor in the late 1970's, clocks and watches now contain a small, special-purpose computer with a program that counts the cycles, and translates them into an electrical form to drive the visible display.
		One practical issue for the mass-production of quartz oscillators was how to adjust their frequency without requiring a human operator to fine-tune them.
