Briefly: Quartz watches are independent and will function without our attention quartz watchQuartz watches use a crystal of quartz (silicon dioxide) shaped like a small bar. This is a ‘piezoelectric’ material – when bent or compressed it generates a small electric field (and vice versa). The crystal is formed to have a natural oscillation at around 32,000Hz. These oscillations generate small electrical signals which are ‘divided down’ by the circuit within the watch to the required frequency (usually seconds) and translated into pulses which are sent to the watch display or a motor to move the seconds hand. The advantage of quartz watches is their simplicity and accuracy – crystals maintain their frequency over broad operating conditions and are cheap to make. They are battery powered and, because they use so little electricity, the battery can often last several years before you need to replace it.Quartz watches have gears inside them to count the seconds, minutes, and hours and sweep the hands around the clockface. But the gears are regulated by a tiny crystal of quartz instead of a swinging pendulum or a moving balance wheel. Gravity doesn’t figure in the workings at all so a quartz clock tells the time just as well when you’re climbing Mount Everest as it does when you’re at sea.Quartz sounds exotic, but it’s actually one of the most common minerals on Earth. It’s made from a chemical compound called silicon dioxide (silicon is also the stuff from which computer chips are made), and you can find it in sand and most types of rock. Perhaps the most interesting thing about quartz is that it is piezoelectric: if you squeeze a quartz crystal, it generates a tiny electric current. The opposite is also true: if you pass electricity through quartz, it vibrates at a precise frequency (it shakes about an exact number of times each second). Inside a quartz clock or watch, the battery sends electricity to the quartz crystal through an electronic circuit. The quartz crystal oscillates (vibrates back and forth) at a precise frequency: exactly 32768 times each second. The circuit counts the number of vibrations and uses them to generate regular electric pulses, one per second. These pulses can either power an LCD display (showing the time numerically) or they can drive a small electric motor (a tiny stepping motor, in fact), turning gear wheels that spin the clock’s second, minute, and hour hands.Quartz watches gain or lose seconds here and there. Quartz vibrates at a slightly different frequency at different temperatures and pressures so its timekeeping ability is affected to a tiny degree by the warming, cooling, ever-changing world around us. In theory, if you keep a watch on your wrist all the time (which is at more or less constant temperature), it will keep time better than if you take it on and off (causing quite a dramatic temperature change each time).Quartz watches are independent and will function without our attention. If we left it in a drawer for a year, it will still run. It will still be accurate we can take it for granted, and it does not need us. By nature, they are cool and aloof and so are our reactions, they fail to touch our hearts in the deepest sense.Highlights*Quartz watches completed its 40th birthday in December 2009*Seiko introduced the world's first quartz watch, called Quartz Astron*Hamilton introduced the worlds' first digital watch.

The prestigious Gold Seamaster Aqua Terra Co-Axial Chronometer was presented to the winner together with the Arabian coffee-pot shaped tournament trophy, following a thrilling final day which required three play offs between the Spaniard and Europe number one Briton Lee Westwood, both tied at 11 under par at the completion of the fourth round. This was the first time in the event's 21-year history that the Dubai Desert Classic had an internationally renowned brand as its title sponsor in a deal which will continue for the next four years as "OMEGA Dubai Desert Classic". "We are delighted to present this exquisite timepiece to Jimenez. OMEGA's title sponsorship of Dubai Desert Classic is in line with our global marketing strategy of targeting high profile sporting events staged in high-growth markets," said Mr. Raynald Aeschlimann. OMEGA's association with high profiled international sporting events goes back a long way. Its involvement with world class golf events About the Winner's Watchincludes its title sponsorship of the Omega Mission Hills World Cup, the oldest and most prestigious global golf team event in the world, and the Omega European Masters in Crans-Montana, Switzerland, which has attracted the finest of professional golfers for over a decade. Omega is also the title sponsor of the China Tour.OMEGA to present a Seamaster Aqua Terra Co-Axial Chronometer to the winner of the Dubai Desert Classic.The stunning Seamaster Aqua Terra Co-Axial Chronometer is distinguished by the "teak-concept" vertical lines on its dial which are reminiscent of the wood decks of luxury boats. The winner's watch is presented with an 18 Ct red gold case and a brown leather alligator leather strap.What is inside the 41.5 mm case is every bit as impressive: the watch is equipped with OMEGA's exclusive Co-Axial calibre 8501, one of the movements which signalled a revolution in the way mechanical wristwatches are being made. Its official certification as a chronometer is a testimony to its outstanding timekeeping performance. The Co-Axial calibre 8501 is well suited to professional golfers whose careers take them all over the world. The hour hand can be changed independently of the other hands, making adjustments to different time zones very easy. The Aqua Terra Co-Axial Chronometer features a sapphire caseback which makes it possible to watch the movement in action and to marvel at its exquisite detail. The watch is water-resistant to 150 metres (500 feet).OMEGA's Seamaster Aqua Terra watches have attracted an enthusiastic following with their artful blend of innovative technology and elegant but sporty design. As much at home on the decks of the luxury boats recalled by their dials as they are on the golf course, they truly live up to their name.The winner of this year's OMEGA Dubai Desert Classic will claim not only the tournament's championship trophy and check, but also an extraordinary timepiece crafted by the tournament's title sponsor.
