They are known for their accuracy, reliability, efficient energy consumption, and relatively low maintenance requirements. Yet quartz is sometimes described simply as the easier alternative to a mechanical movement.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">But the technology behind it is more sophisticated than that.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">A quartz watch combines a quartz crystal, an electronic circuit, a power source and, in analogue watches, a stepping motor and gear train.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Together, these components create a highly <strong>stable system for measuring time<\/strong>.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Understanding how a <strong>quartz watch works<\/strong> is useful not only for watch enthusiasts, but also for brands developing their own collections. The <strong>choice of movement can influence the dimensions<\/strong>, functions, battery life, design and technical characteristics of the finished timepiece.<br><br>But the movement is only one part of the process: technical development, prototyping, component selection, assembly, testing and quality control all contribute to the final product. TAN SA supports brands throughout <a href=\"https:\/\/tanchiasso.ch\/en\/production-process\/\"><strong>all these stages, from initial development to the finished timepiece.<\/strong><\/a><\/p>\n\n\n\n<h2 class=\"wp-block-heading\">How a Quartz Watch Works: The Crystal and Frequency<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">At the heart of a conventional quartz watch is a small quartz crystal. Quartz has piezoelectric properties: when an electrical voltage is applied, the crystal oscillates at a very stable frequency.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">A typical <strong>Swiss quartz watch uses a crystal oscillating at 32,768 Hz, or 32,768 oscillations<\/strong> per second. An electronic circuit repeatedly divides this frequency until it produces one electrical pulse per second.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">In an analogue quartz watch, this pulse activates a stepping motor. The motor converts the electrical impulses into mechanical movement, advancing the gear train and moving the second, minute and hour hands.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">This is the fundamental principle behind a <strong>quartz crystal watch<\/strong>. Instead of using a mechanical balance wheel and escapement as the timing reference, the movement relies on the stable oscillation of quartz.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Why 32,768 Hz?<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">The frequency of 32,768 Hz is particularly practical because it is a power of two: 2\u00b9\u2075. The electronic circuit can therefore divide the frequency by two fifteen times to obtain one pulse per second.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">This <strong>stable oscillation of quartz<\/strong> provides a highly consistent timing reference, which is one of the main reasons conventional quartz watches can <strong>achieve greater everyday accuracy<\/strong> than most mechanical watches.&nbsp;<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The Federation of the Swiss Watch Industry describes quartz watches as having a variation of less than one second per day, although actual performance depends on the specific movement.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Battery and Maintenance: What You Need to Know<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">A conventional <strong>quartz watch uses a small battery<\/strong> to provide the electrical energy required by the electronic circuit and stepping motor. Battery life depends on:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>the movement,\u00a0<\/li>\n\n\n\n<li>battery capacity,&nbsp;<\/li>\n\n\n\n<li>functions,<\/li>\n\n\n\n<li>construction of the watch.<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">Depending on the calibre, a quartz watch battery can last several years. In a conventional battery-powered quartz watch, the watch eventually stops when the battery is depleted.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Replacing a quartz watch battery<\/strong> is generally a straightforward operation, but opening the case can affect its water resistance. Professional battery replacement may therefore include checking the seals and, where appropriate, testing the water resistance of the case.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Not all quartz watches use conventional disposable batteries. <strong>Solar quartz watches use photovoltaic cells<\/strong> to convert light into electrical energy, which is stored in a rechargeable cell. This can significantly <strong>reduce the frequency of battery replacement.<\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Quartz therefore does not mean maintenance-free. Seals, gaskets, batteries or rechargeable cells and mechanical components can still require inspection or replacement during the life of the watch.<\/p>\n\n\n\n<figure class=\"wp-block-image size-full\"><img fetchpriority=\"high\" decoding=\"async\" width=\"1024\" height=\"683\" src=\"https:\/\/tanchiasso.ch\/wp-content\/uploads\/2026\/09\/Immagine-quartz2.png\" alt=\"\" class=\"wp-image-1771\" srcset=\"https:\/\/tanchiasso.ch\/wp-content\/uploads\/2026\/09\/Immagine-quartz2.png 1024w, https:\/\/tanchiasso.ch\/wp-content\/uploads\/2026\/09\/Immagine-quartz2-300x200.png 300w, https:\/\/tanchiasso.ch\/wp-content\/uploads\/2026\/09\/Immagine-quartz2-768x512.png 768w\" sizes=\"(max-width: 1024px) 100vw, 1024px\" \/><\/figure>\n\n\n\n<h2 class=\"wp-block-heading\">Quartz Accuracy vs Mechanical Watches<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Quartz watch accuracy<\/strong> is one of the principal technical advantages of the technology.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">One of the key reasons for this difference is the frequency at which the timing element oscillates. A conventional quartz crystal oscillates at 32,768 Hz, or 32,768 cycles per second. By comparison, the balance wheels of most mechanical watches typically operate at around 3 or 4 Hz, equivalent to 21,600 or 28,800 vibrations per hour.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The much <strong>higher frequency of quartz<\/strong> gives the electronic circuit a much <strong>finer timing reference<\/strong>, while the stability of the oscillator helps <strong>maintain consistent timekeeping<\/strong>. Together, the stable quartz oscillator and electronic control allow conventional quartz watches <strong>to achieve much smaller deviations<\/strong> in timekeeping than most mechanical watches.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><a href=\"https:\/\/tanchiasso.ch\/en\/how-a-mechanical-watch-works-complete-guide\/\"><strong>Mechanical movements<\/strong><\/a> use a balance wheel and escapement to regulate the release of energy from the mainspring. Their accuracy can be influenced by factors such as position, temperature, magnetism, shocks, lubrication and adjustment.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The comparison is therefore not simply a question of quality. <strong>Quartz and mechanical<\/strong> movements represent <strong>two different approaches to timekeeping<\/strong>, with different priorities in terms of precision, energy consumption, construction and functionality.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">For brands, the <strong>appropriate choice depends on the intended character of the watch<\/strong>, its functions, dimensions, design and technical requirements.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Analogue and Digital Quartz: Practical Differences<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Quartz technology can be used in both analogue and digital watches.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">An <strong>analogue quartz watch<\/strong> uses a traditional dial and hands. The electronic circuit sends a signal to the stepping motor, which converts the electrical impulses into mechanical movement and advances the hands.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">A <strong>digital quartz watch<\/strong> displays the time electronically, usually through an LCD or another electronic display. The quartz oscillator and electronic circuit still regulate the measurement of time, but there is no need to convert the signal into the mechanical movement of hands.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The <strong>main difference is therefore the display system<\/strong> rather than the fundamental principle of timekeeping.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Both <strong>analogue and digital quartz watches<\/strong> can incorporate <strong>additional functions<\/strong>, including calendars, chronographs, alarms, multiple time zones and other electronic features.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">How Long Does a Quartz Watch Last?<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">The lifespan of a quartz watch depends on the quality of its components, the movement used, the conditions in which it is worn and how well it is maintained.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Quartz movements generally have fewer mechanically interacting components than traditional mechanical movements, which can reduce certain forms of mechanical wear. However, electronic components, batteries, seals and other parts can still deteriorate over time.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">A well-made <strong>quartz watch can remain functional for many years<\/strong> when properly maintained. Replacing the battery when necessary, protecting the watch from excessive moisture and impacts and checking its seals can all contribute to its longevity.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The lifespan of the complete timepiece also depends on components outside the movement, including the case, crystal, crown, dial, hands and gaskets.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">For this reason, the <strong>durability of a quartz watch<\/strong> should be considered as the result of the quality of the entire timepiece rather than the movement alone.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Quartz Watch FAQs<\/h2>\n\n\n\n<h3 class=\"wp-block-heading\">Why does a quartz watch tick once per second?<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">The characteristic <strong>one-second movement<\/strong> of a quartz watch&#8217;s second hand comes from the way the movement converts the electronic timing signal into mechanical motion. Unlike a mechanical watch, whose seconds hand can appear to move continuously or in several smaller steps depending on the escapement, a conventional quartz movement typically advances the hand in one-second increments.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Some quartz movements, however, use a different stepping system and can produce smoother or more frequent movement of the second hand. The motion of the hand therefore depends on the design of the movement rather than on quartz technology alone.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Does a quartz watch have jewels?<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Some quartz movements contain jewels, although they generally use fewer than mechanical movements. Jewels are <strong>synthetic ruby or sapphire bearing surfaces<\/strong> placed at specific points in the movement, particularly where the pivots of rotating components are supported.&nbsp;<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">They <strong>reduce friction and wear<\/strong> at these bearing points rather than simply being placed between any two components that come into contact.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The number of jewels depends on the architecture and functions of the calibre. For example, some <strong>quartz movements can have anywhere from a few jewels to 10 or more<\/strong>, while many conventional mechanical movements have around 17 to 25 jewels, depending on the design and complications.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Jewels can therefore contribute to reducing friction and wear, but the number of jewels should not be treated on its own as a direct measure of movement quality. Their value is determined by where and why they are used within the movement&#8217;s architecture.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Can a quartz watch movement be repaired?<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">It depends on the calibre and the type of fault. Some quartz movements are designed to be repaired or serviced, while in other cases replacing the complete movement may be the most practical solution.&nbsp;<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The decision depends on the construction of the calibre, the availability of spare parts and the age and condition of the watch.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">What is a Swiss quartz movement?<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">A <strong>Swiss quartz movement<\/strong> is a quartz movement that meets the applicable requirements for classification as a Swiss movement. These requirements concern factors such as technical development, assembly, inspection and the Swiss value of the movement.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">A Swiss quartz movement should not automatically be confused with a <a href=\"https:\/\/tanchiasso.ch\/en\/swiss-made-watches-the-excellence-of-swiss-watchmaking\/\">Swiss Made watch<\/a>. The <strong>Swiss Made designation<\/strong> applies to the complete timepiece and requires additional conditions to be fulfilled, including requirements concerning technical development, casing-up, final inspection and the proportion of Swiss manufacturing costs.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Why does a quartz watch gain or lose time?<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Although quartz watches are <strong>highly accurate<\/strong>, they can still show small variations in timekeeping. Factors such as temperature, battery condition, component tolerances and the characteristics of the oscillator and electronic circuit can affect the rate of the movement. The amount of variation depends on the calibre and its technical design, while advanced movements may use technologies such as temperature compensation to improve accuracy.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Conclusion<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Quartz technology offers a practical combination of precision, efficient energy consumption and relatively low maintenance, while its electronic architecture allows manufacturers to integrate different functions and configurations into a watch.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Rather than being simply an alternative to mechanical watchmaking, quartz represents a different approach to timekeeping, with its own technical characteristics and applications. For brands, understanding these differences is an important part of defining the movement, specifications and functionality of a new timepiece.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The right movement ultimately depends on the concept, design and technical requirements of each watch.
