What Is An Atomic Solar Watch And Who This Is For
One of the most important treasure is time. Time is a man’s leverage to weigh in both success and failure. It is considered as the most limited and the most neglected resource. History began when ancient people predicted time by watching the position of the sun. They could forecast when would be the best season for planting, for fishing, for farming, etc. until great minds were born, and they created one thing that made the world as it is today – watches.
Watches are far known as an instrument for timekeeping. You can go anywhere and travel to many places and still aware of your urgent meeting on a particular day and time.
So, what is an atomic solar watch? From the word solar, its sources are both natural and human-made light. Mr. Sun emits radiation, which translates radio waves through a spectrum. Uncle Bulb is the top-rated example of a human-made light. These sources of energy are converted into electricity.
This electricity moves the atomic solar watch’s battery and makes it power on. Timekeeping looks excellent, especially when this solar-powered timepiece is durable and has a very lightweight.

Because of this, it is undeniable to have the most suitable features, especially in solar watches made by quality materials.
How We Picked And Tested
Solar-powered watches are some of the latest innovations around for watches. They use PV solar cells to collect light energy, which it will then convert to power. They are powered, partially or entirely, by light. They are with a solar panel that absorbs the sun, which turns into electrical energy to work. The energy is then stored to the rechargeable battery, so these watches still work even when dark.
Plus, some of the high-end models of atomic watches can work for months without light exposure. These are with li-ion cells. Nevertheless, you must pick one that matches your needs to take advantage of this innovation. The following are some help to choose an atomic watch, like a Seiko solar atomic watch.
The atomic watch must also easy to recharge. There is nothing more frustrating than using one that is difficult to recharge. For the most part, a good-quality one can be recharged in three minutes daily. Others do not need it for nine months. Also, these watches can be recharged using other sources of light, aside from sunlight.
The watch should also have a long lifespan. As you might know, it is not that cheap. So, you should get the most value out of your spending. Compare your options in the durability of the watch by reading user reviews as well as those earlier.
Much like other solar products with a battery component, you should check for the battery as one of the factors to consider. You should know how good it is and its lifespan. It is always better to find a watch equipped with a long-lasting battery, although it might come a little bit expensive.
Divers and other outdoor enthusiasts, among other on-the-go people, prefer a watch with water resistance up to a certain depth. There is no doubt that the unexpected weather can surface. There can also be instances when you must submerge the watch or get it wet. It will be better to look for an atomic solar watch for men that is rated with specific water resistance.
Some people don’t find an issue with a little heavy watch, but not for others who prefer the lighter counterpart. So, in terms of weight, it is much of choice. Nevertheless, many of these watches tend to be on the heavy side, so you should check the weight of the products you’re comparing to find your perfect match.
When looking for men’s solar atomic watches, you should find those that require no maintenance. A few of these need calibration or adjustments from time to time, but not for all.
Frequently Asked Questions
Are solar watches better than battery?
Yes, solar atomic time keeping watches are better than traditional battery-operated quartz timepieces and even clocks with mechanical/automatic movements.
Like quartz watches, solar clocks have lithium batteries but will not require frequent replacement because light (any light will do) keeps the power cell fully charged. After roughly a few hours of light, some solar clocks can run continuously for up to half a year without recharge.
On that note, solar wrist watches retain the quartz timepiece’s remarkable accuracy without requiring battery replacement for up to half a century, thus being more eco-friendly. And with
Solar watches are also more durable than other battery-powered wristwatch types. There is no need to wind a dial or to access the lithium power cell. These actions (or lack thereof) keep the wristwatch intact and improve its water resistance and longevity.
Efficiency is another attribute that solar watches have over other clock types. Mechanical wristwatches require users to wind the dial frequently for continuous usage. On the other hand, automatic timepieces require movement to ensure efficient timekeeping. Solar watches need neither action because they are fully independent.
How accurate is an atomic watch?
Atomic clock watches are the most precise timepieces in the world. According to the National Institute of Standards and Technology, the latest-generation atomic clock (strontium atomic clock) has a yearly accuracy of one-15-billionth of a second.
Of course, not all atomic watches synchronize with strontium. Still, atomic clocks would be more accurate than mechanical, automatic, and quartz watches.
For example, standard quartz watches are accurate to 20 seconds per month, give or take. Meanwhile, certified mechanical timepieces are precise to within more or less 3 seconds per day. On the other hand, automatic clocks have a daily accuracy of +/-10 seconds.
For instance, you can compare the performance between a Citizen atomic solar watch, a Citizen Solar Tech 180, and a Seiko 43R5 Automatic. The atomic device will only deviate by 1.9 seconds over 9 days, while the Solar Tech will have a 19.5-second deviation. The Automatic, on the other hand, is expected to diverge for 1 minute 42 seconds over 13 days.
Does the atomic clock still broadcast?
Yes, the National Institute of Standards and Technology still broadcasts the WWVB code the organization first aired on July 5, 1963, to atomic watches everywhere. Although there have been increases in signal strength, the synchronization process remains the same.
A newly-introduced atomic radio controlled watch receives the coded signal, decodes and translates the message, and synchronizes the time automatically. With such technology, keeping atomic solar watches accurate has become easier than ever.
How long does it take to fully charge a solar watch?
The charging time of solar-powered radio-controlled watches depends on the brand, battery power level, and light source.
For example, Casio’s solar watches can reach a full charge after 18 hours of direct sunlight with a fully-drained or low-power battery. Exposing these timepieces to the sun’s rays through the window can prolong the charging time to 87 hours. On a cloudy day, leaving the clock by the window would require 176 hours to charge.
However, given that you only have about ten to eleven hours of sunlight during the day, 87 hours could translate to 8-9 days of continuous charging through the window.
