If you're looking for a watch that is durable and reliable, you've definitely found the right model in a Breitling Colt Quartz. Its striking design exudes an impressive sovereignty and is instantly captivating. A73380): With a Breitling Colt Quartz, you purchase a premium timepiece. unlikely to increase in value over time.The differences between mechanical and quartz watches are collected in the following table. Like everything else in life, the question of whether one should choose a quartz or a mechanical watch is ultimately a question of personal taste. From a technical point of view, a quartz watch is by no means "cheaper" than a mechanical watch, but above all, it is simply different. However, the quartz watch's dependence on separate energy sources such as a battery has given the watches a bad reputation, as battery-powered quartz movements are more harmful to the environment than mechanical movements. Additionally, a quartz movement does not normally require any maintenance – it is sufficient to change the energy source about every two to three years, which saves time and money. In principle, quartz watches run much more accurately than mechanical watches and have significantly less deviation, making them extremely reliable and robust timepieces for everyday use. Even if a quartz watch stops, the crystal continues to oscillate, only then the gear train can no longer transfer this impulse evenly to the second hand. Quartz also has the advantage that it can hold this frequency well enough to compensate for any deviations. Due to the high frequency, the watch runs very accurately. It serves as a master clock, comparable to the balance wheel in mechanical watches, for the coil and translates this frequency into movements that are passed on to the hands by the gear train. This has the form of a tuning fork and oscillates at an average frequency of 32,768 Hz. ![]() Instead of a spring, quartz watches have a battery that powers the quartz crystal rather than a balance wheel. In terms of its construction, a quartz watch works like a mechanical watch – only it has different components. To put it simply, a quartz movement is driven by electrical impulses, while an automatic movement is driven by mechanically stored energy in the mainspring. Miller, whose model still forms the basis for many quartz movements today.īREITLING COLT CHRONOGRAPH II A73387 What is the difference between quartz watches and mechanical watches? The general structure of the piezoelectric circuit was considerably simplified in 1922 by George W. In other words, there would be no quartz watch without piezoelectricity. ![]() Discovered in 1880 by Pierre and Jacques Curie, the piezoelectric effect states that the deformation of certain metals and crystals, such as quartz, generates electrical energy. One often reads in connection with quartz watches that they are driven by piezoelectricity. Likewise, if its vibration level is too weak, the power supply is increased. This process also ensures high accuracy and smooth operation: if the fork oscillates too much, less energy is supplied to the tuning fork. The movement is driven by two drive coils, which are activated by a transistor, which is activated by the permanent magnets on the fork prongs. For comparison, the escapement wheel of a mechanical watch needs six seconds for a complete rotation. ![]() This is equipped with up to 300 teeth and rotates once around its own axis within 5/6 of a second. In the Accutron, the tuning forks are coupled with a pawl that drives a ratchet wheel. These watches worked with two tuning forks, which were energized and forced to oscillate via two electromagnets. The first model of this kind was the Accutron by Bulova, which was developed by engineer Max Hetzel in the 1950s. The predecessors of quartz watches were tuning fork watches. PATEK PHILIPPE NAUTILUS 7011/1G The predecessor to the quartz watch: The Bulova Accutron The flood of cheap quartz watches resulted in the so-called quartz crisis, which almost caused the entire watch industry to collapse. While quartz watches initially sold for high prices shortly after their introduction on the watch market, they were available and very affordable for everyone not long after. The movement is therefore commonly known as a quartz movement. But do you know what actually constitutes a quartz watch and how a quartz movement works? In this article, we would like to take a closer look at the history and functioning of quartz watches and examine these aspects in greater detail.Ī quartz watch is basically a fully electronic watch, also called a real-time watch, which is driven by an oscillating quartz crystal. By Info Watchmaster, 29 July 2022Everyone knows them and many people own them: quartz watches.
