Modern designs are so sleek and\nfashionable that you wouldn&rsquo;t even know they&rsquo;re solar powered by looking at\nthem. Just because something is new, however, doesn&rsquo;t necessarily mean it&rsquo;s\nbetter than previous versions.<\/p>\n\n\n\n<p>Are solar powered watches reliable? <strong>Yes, solar powered watches charge whenever\nthe watch face is exposed to either natural or artificial sunlight, and excess\nenergy is stored in lithium-ion batteries so the watch can work in the dark as\nwell. The lithium-ion batteries can store enough energy to run from 30 days to\n3,175 days (over 8 years), depending on the model. Failing this, most solar\npowered watches also have a backup battery that can hold up to 80% of its\ncharge for 10 years.<\/strong><\/p>\n\n\n\n<figure class=\"wp-block-image size-full\"><noscript><img loading=\"lazy\" decoding=\"async\" width=\"924\" height=\"616\" src=\"https:\/\/solarpowergenie.com\/wp-content\/uploads\/2019\/12\/are-solar-powered-watches-reliable-1024.jpg\" alt=\"Are Solar Powered Watches Reliable?\" class=\"wp-image-883\" srcset=\"https:\/\/solarpowergenie.com\/wp-content\/uploads\/2019\/12\/are-solar-powered-watches-reliable-1024.jpg 924w, https:\/\/solarpowergenie.com\/wp-content\/uploads\/2019\/12\/are-solar-powered-watches-reliable-1024-300x200.jpg 300w, https:\/\/solarpowergenie.com\/wp-content\/uploads\/2019\/12\/are-solar-powered-watches-reliable-1024-768x512.jpg 768w\" sizes=\"(max-width: 760px) calc(100vw - 20px), 720px\"><\/noscript><img loading=\"eager\" decoding=\"async\" width=\"924\" height=\"616\" src=\"data:image\/svg+xml,%3Csvg%20xmlns='http:\/\/www.w3.org\/2000\/svg'%20viewBox='0%200%20924%20616'%3E%3Crect%20width='924'%20height='616'%20style='fill:%23e3e3e3'\/%3E%3C\/svg%3E\" alt=\"Are Solar Powered Watches Reliable?\" class=\"wp-image-883 eager-load\" sizes=\"(max-width: 760px) calc(100vw - 20px), 720px\" data-pin-media=\"https:\/\/solarpowergenie.com\/wp-content\/uploads\/2019\/12\/are-solar-powered-watches-reliable-1024.jpg\" id=\"mv-trellis-img-1\" data-src=\"https:\/\/solarpowergenie.com\/wp-content\/uploads\/2019\/12\/are-solar-powered-watches-reliable-1024.jpg.webp\" data-srcset=\"https:\/\/solarpowergenie.com\/wp-content\/uploads\/2019\/12\/are-solar-powered-watches-reliable-1024.jpg.webp 924w, https:\/\/solarpowergenie.com\/wp-content\/uploads\/2019\/12\/are-solar-powered-watches-reliable-1024-300x200.jpg.webp 300w, https:\/\/solarpowergenie.com\/wp-content\/uploads\/2019\/12\/are-solar-powered-watches-reliable-1024-768x512.jpg.webp 768w\" data-svg=\"1\" data-trellis-processed=\"1\"><\/figure>\n\n\n\n<p>It&rsquo;s arguable that solar powered watches are\nthe most reliable. They don&rsquo;t require daily winding or the replacement of\nbatteries after a few months. When manually wound or battery powered watches\noperate on insufficient power, they can run at a reduced speed, resulting in\nthe watch becoming more and more &ldquo;late&rdquo; relative to the actual time the longer\nthe power is low. By charging while in use, solar powered watches can prevent\nthis loss of accuracy, provided that the power source is reliable.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Do Solar Powered Watches Work?<\/h2>\n\n\n\n<p>There are many failsafe that make sure that\nsolar powered watches work and keep working for a long time, even if they\naren&rsquo;t in direct sunlight at all times. To understand how solar powered watches\nwork, we should first have an understanding of how solar power works.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">How Solar Power Works<\/h3>\n\n\n\n<p>Because the transformation from sunlight into\nusable electricity takes place out of sight within the photovoltaic cells of\nthe solar panel, it seems that the conversion is done by magic. The process by\nwhich photovoltaic cells create electricity from light, however, is actually\nfairly simple.<\/p>\n\n\n\n<ol><li><strong>Light activates the solar panel.<\/strong> Both natural sunlight and light from artificial sources like incandescent and even fluorescent light bulbs are able to activate the panels and initiate the production of electricity.<\/li><li>The light is absorbed by a semiconducting material, usually silicon. As a result, <strong>electrons are knocked loose from the silicon<\/strong> (or other semiconducting material).<\/li><li><strong>The electrons begin to flow, forming an electrical current.<\/strong> The silicon in the photovoltaic cells is arranged into two layers. Each layer is treated, or &ldquo;doped,&rdquo; in such a way that one layer has a net positive, and the other has a net negative electrical charge, resulting in the loose electrons flowing in one direction, creating a direct current (DC) electrical current.<\/li><li><strong>The electrical current is captured<\/strong> by metal panels on the sides of each cell and transferred into wires. This electricity is used to power the movement of the watch, and any surplus energy is used to charge a lithium-ion battery.<\/li><\/ol>\n\n\n\n<p>Because the energy created in the photovoltaic\ncells is direct current (DC) power, the same type used by both the watch and\nthe lithium-ion battery, there is no need to invert it into alternating current\n(AC) energy as is the case when solar panels are used to power homes.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Lithium-Ion Batteries<\/h3>\n\n\n\n<p>Though the basic chemistry behind lithium-ion\nbatteries was discovered by Gilbert Lewis (1875&ndash;1946), an American chemist, in\n1912, they didn&rsquo;t become widely used until the early 1990s when lithium-ion\nbatteries started being used in cell phones and laptop computers.<\/p>\n\n\n\n<p>Traditional batteries create an electrical\ncurrent by making use of a chemical reaction that happens in only one\ndirection, so when the chemical reaction is done, the battery is no longer\nuseful and must be thrown away in a responsible manner. Lithium-ion batteries, on\nthe other hand, can be recharged to provide mobile power over and over again.\nTypically lithium-ion batteries can be recharged hundreds of times and last up\nto 10 years.<\/p>\n\n\n\n<p>Lithium-batteries store energy in the form of\nlithium ions traveling between a positive electrode made of lithium-cobalt\noxide (LiCoO2) or, in newer batteries, from lithium iron phosphate (LiFePO4)\nand a negative electrode generally made from carbon (graphite). Electrons move\nthrough wires around the cells in the opposite direction as the lithium ions\nare traveling, creating an electrical current.<\/p>\n\n\n\n<p>Not only can lithium-ion batteries be\nrecharged hundreds of times, but unlike nickel-cadmium (NiCd) they do not\nsuffer from a problem known as the &ldquo;memory effect&rdquo; in which NiCd\nbatteries appear to become harder to charge unless they&rsquo;re discharged fully\nfirst. Also, because lithium-ion batteries don&rsquo;t contain the toxic, heavy metal\ncadmium, they are better for the environment.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Backup Batteries<\/h3>\n\n\n\n<p>Even though solar powered watches charge\nwhenever the face is exposed to light (both natural and artificial), and\nlithium-ion batteries can hold a charge for anywhere from 30 days to 3,175 days\n(over 8 years) depending on the model, most solar powered watches also have an\nadditional battery to act as a backup.<\/p>\n\n\n\n<p>These disposable batteries are there to power\nthe watch if all else fails, so of course, they need to work when needed.\nStudies have shown that these batteries can hold up to 80% of their charge for\nup to 10 years. This means that even if your watch were kept away from any\nsource of light (such as stuffed in a drawer, perhaps) long enough to use up\nthe lithium-ion&rsquo;s power reserve, there would still be a backup battery to\nsupply power to run the watch for another few months.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Power Saving Mode<\/h3>\n\n\n\n<p>Many models of solar powered watches have a\npower saving feature that allows the watch to conserve energy when light\nsources are not available. When in power saving mode, the watch ceases the\nconstant supply of energy used to move the watches second hand so that energy\ncan be conserved to maintain its high functions (such as keeping track of the\ndate and day of the month and week) for a longer period of time.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Reliability<\/h3>\n\n\n\n<p>Watches that are not run on solar power\nsometimes run at low power. When a traditional battery is nearly empty and\nneeds to be replaced, or a manual watch needs to be wound, the watch motor may\nrun at reduced capacity. <\/p>\n\n\n\n<p>Because the watch&rsquo;s motor must run at a\nspecific rate in order to keep accurate time, the longer and more often the\nwatch runs at reduced power, the further the watch will be from telling the\naccurate time because the motor will have spent more time running at a lower\nthan accurate pace.<\/p>\n\n\n\n<p>Solar powered watches do not have this problem\nbecause they constantly recharge any time their faces are exposed to natural or\nartificial light, so it&rsquo;s only under extreme conditions that they ever run at a\nnearly empty battery capacity.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">The Pros and Cons of Solar\nPowered Watches<\/h2>\n\n\n\n<p>Though solar powered watches have been\navailable since the 1970s, they are still not as popular are traditional\nbattery powered watches. Newer solar powered models, however, are becoming more\nfashionable. When considering purchasing a solar powered watch, it&rsquo;s important\nto consider the pros and cons.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Pros of Solar Powered Watches<\/h3>\n\n\n\n<p>There are several positives unique to solar\npowered watches.<\/p>\n\n\n\n<ul><li><strong>They are easy to charge<\/strong>. There is no need to remember to change the battery every few months\nor plug them into a charger at night. As long as they are not stored in total\ndarkness, solar powered watches are nearly always charging.<\/li><li><strong>They can be charged by any\nlight source.<\/strong> It&rsquo;s not only natural sunlight that can\nbe used by photovoltaic cells to create electrical power. Solar powered watches\ncan also charge via incandescent and even fluorescent light sources.<\/li><li><strong>They are easy to maintain.<\/strong> Because they are easy to charge and the batteries can last over a\ndecade, solar powered watches rarely require any form of maintenance.<\/li><li><strong>They are more eco-friendly.<\/strong> Because of their rechargeable lithium-ion battery, solar powered\nwatches result in the disposal of fewer traditional batteries, which can\ncontain corrosive or toxic chemical remnants. nickel cadmium (NiCd) batteries,\nfor example, contain the toxic heavy metal, cadmium.<\/li><\/ul>\n\n\n\n<h3 class=\"wp-block-heading\">Cons of Solar Powered Watches<\/h3>\n\n\n\n<p>The benefits of solar powered watches do come\nat a price, however, and this can mean that <strong>solar powered watches are more\nexpensive<\/strong> than others.<\/p>\n\n\n\n<p>Though the technology has and continues to\nimprove and become more affordable, the solar panel technology they rely on makes\nsolar powered watches more expensive than traditional quartz watches. This\ninitial cost may be offset by the savings of not having to buy replacement\nbatteries every few months.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">A Brief History of Solar Powered\nWatches<\/h2>\n\n\n\n<p>The earliest solar powered watches, created in\nthe 1970s, required relatively large, dedicated photovoltaic panels on the\nwatch face. Because the solar power technology was still in its infancy, these\ncells had rather large to generate enough power to run the watch. <\/p>\n\n\n\n<p>The watch designs had to accommodate these\nlarge panels, which sometimes took up more space of the watch face than the\nscreen that displayed the time. Often solar powered watches were designed in a\nneo-futuristic fashion that was a 1970&rsquo;s attempt to predict the fashion trends\nof the future.<\/p>\n\n\n\n<p>As photovoltaic cell technology improved, the\ncells became smaller and smaller, and were able to be incorporated more subtly\ninto more contemporary designs. Today the solar panel is typically beneath the\nwatch&rsquo;s crystal, with the dial either directly on or a layer above the solar\npanel itself. This allows the entire face to the watch to be both solar panel\nand display. In this way modern solar watches can be made in any design.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Types of Watches<\/h2>\n\n\n\n<p>Just as cars are powered by different types of\nengines (e.g. gasoline, diesel, electric), watches are powered by different\ntypes of movement. Solar powered watches are a type of quartz watch. An\nunderstanding of the various watch movements will make it clear why solar\npowered watches are arguably the most reliable type of watch.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Quartz<\/h3>\n\n\n\n<p>A quartz watch uses an electronic oscillator\nthat is regulated by a quartz crystal to keep time. The crystal oscillator\nconverts direct current (DC) energy from a power source into an alternating\ncurrent (AC) signal with a very precise frequency. <\/p>\n\n\n\n<p>In traditional quartz watches, this power source\nis a battery that will last a few years, then need to be replaced. In a solar\npowered watch the direct current (DC) energy comes from the photovoltaic cells\ndirectly or from the lithium-ion battery storage.<\/p>\n\n\n\n<p>The frequency of the crystal oscillator is\nextremely precise, and its cycles are counted by some form of digital logic in order\nto determine and display the time. Quartz watches are more accurate than\nmechanical watches by at least an order of magnitude. <\/p>\n\n\n\n<p>They are also much less expensive to produce.\nBecause they have electrical components, however, they will eventually fail at\nwhich point it is more economical to replace than repair.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Mechanical<\/h3>\n\n\n\n<p>While quartz watches function electronically,\nmechanical watches use a clockwork mechanism to tell time. Mechanical watches\nare driven by a mainspring that must be wound periodically. Most mechanical\nwatches require manual winding, but automatic watches use the natural movement\nof the wearer to wind the mainspring.<\/p>\n\n\n\n<p>As the mainspring unwinds, its force is transmitted\nthrough a series of gears to power a balance wheel, which is a weighted wheel\nthat oscillates back and forth at a constant rate. An escapement releases the\nwatch&rsquo;s wheels a consistent amount with each swing of the balance wheel. This\nmakes the watches hands move at a constant rate and produces the tell-tale\nticking sound of a mechanical watch.<\/p>\n\n\n\n<p>Mechanical watches are not as accurate as\nquartz watches. Even a simple mechanical watch contains about 130 components\nand periodically needs to be cleaned by a skilled watchmaker. This makes them\nsignificantly more expensive. They are now mostly high-end products typically\nbought as a status symbol.<\/p><p>This article is owned by SolarPowerGenie.com and was first published on November 27, 2019<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Seiko Solar Versus Citizen Eco\nDrive<\/h2>\n\n\n\n<p>The two most popular brands for solar powered\nwatches are Seiko and Citizen. Both are giant Japanese watch brands. These\ncompanies were a big part of the reason the center of the timekeeping universe\nshifted from Switzerland to Asia as quartz movement overtook mechanical\nmovement beginning in the 1970s.<\/p>\n\n\n\n<p>That being said, Citizen is more of a quartz\nbrand, while Seiko is more of a mechanical brand. Citizen has been producing\nsolar powered watches longer, and it&rsquo;s made more advancements in the\ntechnology.<\/p>\n\n\n\n<p>Citizen&rsquo;s Eco Drive technology used in their\nsolar powered watches won the Gold Prize at the Eco mark Awards in 2014. The\nEco Drive watches are also a little less expensive, more widely available,\nwater-resistant to twice the depth, and have a secondary battery that lasts\ntwice as long as watches that use Seiko&rsquo;s Solar system.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Can You Overcharge a Solar\nPowered Watch?<\/h2>\n\n\n\n<p>Solar powered watches are equipped with\novercharge protection functions that make sure that the lithium-ion battery is\nnot damaged when the watch is exposed to light when the battery is already\nfully charged. <\/p>\n\n\n\n<p>Similar features are common on any modern\ndevice that uses a lithium-ion battery, like laptops and cell phones, so they\ncan remain plugged in without harm. Typically when the battery becomes fully\ncharged, the display will show 100%, but power will be diverted away from\ncharging battery any further. When the battery&rsquo;s capacity falls to somewhere\nbetween 95 and 97 percent, charging will resume, but the display will show 100%\nfull the entire time.<\/p>\n\n\n\n<p>The watch can be damaged in situations where\nit is overheated, but it is the heat and not the charging property of the light\nthat causes the problem in these instances.<\/p>\n\n\n\n<p>&nbsp;Avoid\ncharging solar powered watches in the following ways which can result in\noverheating and damage to the watch:<\/p>\n\n\n\n<ul><li><strong>On the dashboard of an automobile<\/strong>&nbsp; &ndash; Cars are notorious for becoming dangerously\nhot saunas when parked in direct sunlight all day. The dashboard gets even\nhotter than the rest of the car&rsquo;s interior (and more quickly) because it is a\nconfined space with a highly reflective surface on bottom and a heat trapping\nglass on top.<\/li><li><strong>Too close to an incandescent light bulb<\/strong> &ndash;\nIncandescent light bulbs create light by passing electricity through an\nextremely thin metal filament, causing the metal to become so hot it glows.\nAnyone who&rsquo;s seen <em>Ferris Bueller&rsquo;s Day\nOff<\/em> (or forgot to study for a test) knows that the bulbs can produce a lot\nof heat.<\/li><li><strong>In direct sunlight for an extended period<\/strong> &ndash;\nThe sun, being a ball of burning gas, also produces a lot of heat as well as\nlight. Though it&rsquo;s significantly further away than a light bulb, anyone who&rsquo;s\ngotten a bad sunburn can tell you how harmful it can be, especially over a long\nperiod of time.<\/li><\/ul>\n\n\n\n<p>Because solar powered watches charge while you\nwear them, there isn&rsquo;t any need to leave them these dangerous situations to\ncharge anyway. If your watch were locked in a dark drawer for enough months (or\nyears) for the battery to fully deplete, you would only need to charge it for a\nlittle bit, just long enough for it to start running again, so you can reset\nthe time (and date, if it has a date window) and begin wearing it again.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">How Long Does it Take to Charge a\nSolar Powered Watch?<\/h2>\n\n\n\n<p>Though you don&rsquo;t need to fully charge your\nwatch in order for it to function, people often wonder how quickly solar\npowered watches charge. The photovoltaic cells of solar powered watches can\nproduce energy from both natural and artificial light, but the former is a lot\nmore efficient than the latter.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Charging Via Natural Sunlight<\/h3>\n\n\n\n<p>Putting a solar powered watch in direct\nsunlight for 3 minutes will produce enough energy to run the watch for 24\nhours. <\/p>\n\n\n\n<p>To fully charge the watches lithium-ion\nbattery from empty would take about 20 hours or more of direct sunlight of a\nwarm climate or season. <\/p>\n\n\n\n<p>During cold seasons in parts of the world\nfurther from the equator, there are not only less hours of sunlight, but the\nsunlight there comes at such a steep angle that a significant percentage of its\nenergy doesn&rsquo;t penetrate the Earth&rsquo;s atmosphere. In such situations, it may\ntake more than 60 hours to fully charge the watch&rsquo;s battery.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Charging Via Artificial Light<\/h3>\n\n\n\n<p>Though photovoltaic cells can produce\nelectricity when exposed to artificial light, it is not nearly as effective. To\ncreate 24 hours&rsquo; worth of power, a watch must be in the sun for 3 and a half\nhours. To fully charge the lithium-ion battery from empty via artificial light\nmay take up to 150 hours.<\/p>\n\n\n\n<p>Solar powered watches typically are fully\ncharged before packages for sale. They are commonly packaged with the watch\nface exposed, which not only displays the watch for sale, but also allows light\nto penetrate the plastic packaging.<\/p>\n\n\n\n<p>Maintaining a charge only takes a few minutes\nof sunlight (or a few hours of artificial light) per day, and the lithium-ion\nbatteries can hold enough charge to last several months or years, so it&rsquo;s\nunlikely that you&rsquo;ll ever need to fully charge a solar powered watch from\nempty.<\/p>\n\n\n\n<p>If you ever do need to charge a solar powered\nwatch&rsquo;s battery from empty, it is suggested that you charge it to at least 85\npercent full before halting exposure to light.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">How Long Will a Solar Powered\nWatch Last?<\/h2>\n\n\n\n<p>The lithium-ion batteries in solar powered\nwatches typically last from 10 to 20 years and do not need to be replaced in\nthe life of the watch. The batteries can be recharged hundreds of times, but\neventually will wear out. <\/p>\n\n\n\n<p>Because solar powered watches are quartz\nwatches, not mechanical watches, when the battery finally does die, it\ntypically makes more sense to replace the watch as opposed to having it\nrepaired or the battery replaced.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">The Best Solar Powered Watches<\/h2>\n\n\n\n<p>Nearly every major watch brand has its own\nsolar powered watches. The technology has advanced so much since they first\nbecame available that modern solar powered watches come in all types of\ndesigns.
