The answer is that the quartz vibrates at a subtly different frequency at different temperatures and pressures. Its time-keeping capability is affected to a small degree by the warming, cooling, ever-changing environment around us. So, in theory, if you keep a watch on your wrist at all times, it is much more or less constant temperature. That watch will keep time better than if you take it on and off your wrist, causing a rather significant temperature shift, in any environment.
It will vibrate when you put electricity to it, and it is going to give you electricity when you vibrate it. The quartz crystal oscillator uses piezoelectricity in both directions — at the same exact time. Making quartz an incredibly efficient power source.
Hence why watch batteries actually last quite a long time. What quartz watches lack in finesse and historic footing they excel in the following three areas:. The pure practicality of quartz is that these watches have a power reserve that literally lasts for a lifetime.
So once you set your watch, you will rarely ever have to touch it again. You can forget your quartz watch on the counter, pick it up six months later, and there it is, ticking away ready to be worn immediately.
Size is a HUGE factor. Because of the smaller sized movement, quartz watches can be slimmer and smaller than automatic watches.
Smaller watch casings are essential when you have a smaller wrist. If you work in manual labor or just enjoy the great outdoors and the potential watch hazards that come with it, then a quartz watch is perfect for you.
Check out the Jack Mason Overland watch , designed for durability and is water resistant up to meters. This watch runs off of premium Japanese quartz. Quartz watches like the Overland can take on a higher impact than mechanical and automatic watches because of their effortless simplicity. There is nothing inside the watch that is going to get thrown off-kilter if you bash your watch into something or take a tumble.
Which is why some of the most robust watches are quartz movement watches. Billions of people use quartz every day, but few realize it because the tiny crystals they use are hidden in their watches and clocks. But what do the clear or whitish crystal rocks found all over the world have to do with timekeeping? Some materials, such as certain ceramics and quartz crystals, can produce electricity when placed under mechanical stress. The most important is that it is piezoelectric.
When quartz is compressed or bent, it generates an electric charge on its surface. It also works the other way: if a small electric charge is applied to quartz, it will compress or bend just slightly. This might not sound too special, but it was to revolutionise the watchmaking profession. This electric charge meant that quartz had an oscillating voltage on its surface. It could oscillate repeat a back and forth movement extremely accurately and for a long time.
On top of that, quartz has an outstanding resilience to temperature. It means that quartz makes for one of the best oscillators. However, it would stop oscillating eventually.
Imagine a bell, which creates a ringing due to vibrations. The bell it hit, the sound is created and gradually fades as the vibrations decrease. People had to find a way to keep the quartz oscillating regularly if it was going to be useful in watchmaking. In , Warren Morrison discovered that, by putting a charge through a quartz crystal, he could keep a steady beat. This was essential for the next few decades of watch developments.
It was found that the electrical charge that is naturally created on the surface of quartz crystal under pressure could be taken off the surface of the material using electrodes and an electric circuit.
The charge is then amplified through a transistor and reapplied to the quartz. The electrical charge continually moved across the quartz and ensured it oscillated constantly. Technology combined with the quartz allowed it to keep oscillating for an extended period of time without losing any energy.
It was the most accurate oscillator ever and the perfect way to power a watch. Every quartz watch therefore requires a battery. The battery sends electricity to the quartz through the circuit. The circuit counts the number of vibrations and uses those to create an electric pulse. Once pulse for every vibrations. One every second. The pulses drive a motor, which turns the hands of the watch. Quartz watches are the best choice for reliability and accuracy.
Quartz turned the watchmaking industry upside down in what was known as the quartz crisis, or the quartz revolution. With this change, there was huge economic upheaval as quartz replaced mechanical watches. It began when a watch called Astron was released. In the late s and into the 60s, Swiss and Japanese watch makers were racing to make the first quartz watch.
So much so, that the Centre Electronique Horloger CEH was established wherein twenty different Swiss watch manufacturers could collaborate to develop the first Swiss-made quartz watch. Seiko, a Japanese company, got their first with a portable quartz clock, which they named the Seiko Crystal Chronometer QC However, it was Seiko that released the first official quartz watch, the Astron, in This began the Quartz revolution - also known as the quartz crisis.
Because the first quartz watch came from Japan, the mechanism through which quartz watches work is often known as Japanese quartz movement.
