Bariho Quartz Women's Wrist Watch Big Numbers Dial Pattern Avant-garde Collectible Design Up for sale is a coolly designed quartz watch (women's) by Bariho. It features big prominent numbers designed on the dial. This is perfect for adults and adolescents alike looking for something different to wear casually. It has a stainless steel body (with battery inside included) along with an elegant white leather strap. Quartz watches and clocks are among the most accurate time pieces in use today. The following is an article by Wikipedia on the technical and scientific background of quartz watches and clocks: ' A quartz clock is a clock that uses an electronic oscillator that is regulated by a quartz crystal to keep time. This crystal oscillator creates a signal with very precise frequency, so that quartz clocks are at least an order of magnitude more accurate than good mechanical clocks. Generally, some form of digital logic counts the cycles of this signal and provides a numeric time display, usually in units of hours, minutes, and seconds. Quartz timekeepers are the world's most widely-used timekeeping technology, used in most clocks and watches, as well as computers and other appliances that keep time. Chemically, quartz is a compound called silicon dioxide. Many materials can be formed into plates that will resonate. However, quartz is also a piezoelectric material, that is, when bent, it develops electrical charges across some planes in its crystal. In a reverse effect, if charges are placed across the crystal plane, quartz crystals will bend. Since quartz can be directly driven (to flex) by an electric signal, no additional speaker or microphone is required to use it in a resonator. Similar crystals were once used in low-end phonograph cartridges: The movement of the stylus (needle) would flex a quartz crystal, which would produce a small voltage, which was amplified and played through speakers. Quartz microphones are still available, though not common. Quartz has a further advantage in that its size does not change much as temperature fluctuates. Fused quartz is often used for laboratory equipment that must not change shape along with the temperature, because a quartz plate's resonance frequency, based on its size, will not significantly rise or fall. Similarly, since its resonator does not change shape, a quartz clock will remain relatively accurate as the temperature changes. In the early 20th century, radio engineers sought a precise, stable source of radio frequencies, and started at first with steel resonators. However, when Walter Guyton Cady found that quartz can resonate with less equipment and better temperature stability, steel resonators disappeared in a few years. Later, scientists at NIST (Then the U.S. National Bureau of Standards) discovered that a crystal oscillator could be more accurate than a pendulum clock.
