What is an atomic solar watch?

As the name implies, these are watches that are charged using energy from the sun, thereby enabling users to enjoy the use of their watches for a long time without the need to change the battery. It is efficient, durable, and aesthetically pleasant

Advantages of solar atomic watch

There are many advantages with solar atomic watches, one of which is that this watch does not need a change of battery from time to time, unlike regular batteries we are used to. The solar battery in it can last decades without the need for a change.

Another advantage is that it tells accurate time. This is made possible because it never stops running, not unless it’s kept in complete darkness for up to six months. So, as long as the watch is running and in constant operation, it will always tell the accurate time.

It is also reliable as it not only takes light from the sun but also converts light from an artificial source into useable energy. Hence, it’s able to charge either with direct sunlight or artificial light; this feature makes it very reliable.

Furthermore, it requires little or no maintenance and is affordable. The icing on the cake is the fact that it is eco-friendly.

How to choose the Best Solar Atomic Watch?

It’s one thing to get an excellent solar atomic wristwatch; it’s another thing to purchase the best solar atomic watch. As easy as it may seem to be, there are factors to consider before making a choice. These factors include:


Technology is always continually improving and becoming better as the day goes by; therefore it is essential to purchase a solar watch that is in sync with the latest technological advancement to prevent problems and enable it to function effectively. 


This is probably the most crucial factor to consider as it determines if you will be purchasing the product or not. It should be noted that most top-quality solar atomic watches are usually the most expensive and I’m sure you want the best, just like everyone else. The question however is, can you afford it? This type of watch is usually bought by those who appreciate quality, so if you are a first-time buyer, you should have a budget before going ahead to buy a watch. This would prevent you from going overboard and having to regret your decision later, not that you would ever regret though, but it’s always best to work with a budget.


The weather can be sometimes unpredictable, one moment the sun is out shining so bright, and the next moment it’s raining cats and dogs. If your solar wristwatch isn’t waterproof, then prepare to say goodbye as it’s sure to get damaged. If on the other hand, it is waterproof, then it prevents water from getting into core components of the watch that may damage it forever. If you are one of those who love to swim, dive, or engage in any surface water sports, then you will need to look out for a solar watch that is waterproof. Luckily most of the watches reviewed in this article are waterproof, but you may want to retake a look at it to be sure.


Watches don’t just tell time; some do more than that. So, it’s essential to question the motive behind the purchase, why are you buying an atomic solar watch in the first place? You may feel like the more functions it can perform, the better for you, however, this is not always the case, not unless you are a frequent hiker or an adventurer who requires GPS to locate your way.

If it’s office wear you are looking for, then a wristwatch that can tell the time and date will do just fine. But, if you need a timer or a stopwatch that can access different time zone or a watch with digital and analog reading, then that’s fine too. It’s your choice in the end and whichever you choose will serve you well.


Different people fancy different things, which is seen as cool by one person may not be so by another. Yes, we know you want a cool wristwatch, but while being cool, ensure the watch is comfortable enough to wear. If the surface of the wristwatch is too big, it may get hooked on things and this may lead to damage to the wristwatch or may cause you to get injured.

Too thick or too thin wristwatches while being cool may look funny on you. In all, before making a purchase ensure you critically look at the design as this would enable you to make the right choice.

Battery life just like functions in a watch varies, the battery life also differs from one type of solar wristwatch to another. Some last for a long time, while others do not last so long, it is essential that before making a purchase, you are guaranteed that the battery will last for a very long time.


One of the reasons you didn’t go for a regular wristwatch but opted for an atomic solar wristwatch is because of its accuracy. Thus, you must purchase a wristwatch that can tell the accurate time, and that would not malfunction within a short time.


This is also important. It makes no sense to buy a wristwatch whose screen is not clear enough to be seen. No matter how beautiful it may look, you are sure to end up frustrated and angry. Therefore, you must purchase a solar atomic watch whose date and time can be seen and understood clearly.

How to Charge an Atomic Solar Watch Fast?

To charge an atomic solar watch, place the watch close to a light source, most preferably daylight. The ideal place to position the watch would be a window ledge or if you are outdoors then place it on your shirt sleeves to expose it to sunlight. To charge the watch completely, it will take up to twenty hours or more under direct sunlight and about sixty hours when the weather is cold.

However, when artificial light is being used to charge, then the hours are long as it requires about 150 hours under artificial light for the watch to fully charge. If you are going to be using artificial light, then it’s best to keep the watch at least 20 inches away from the light.

Temporal Charging

Sometimes we do not have the luxury of time, and yet we need our watch to be charged. What to do? Place the timepiece under direct sunlight for up to three minutes; this would give it 24-hour worth of charging capacity. If you are going to be using artificial light, then leave it for as long as three and a half hours to give it the same 24-hour worth of charging capacity.

This should be done at least once a day to maintain its temporal charging, in the long run, the watch gets fully charged if you keep doing this. Ensure the watch is at least 85% charged before quitting the temporal charging process altogether.

FAQs about Solar Atomic Watch

1. What Are the Differences Between an Atomic Solar Watch And a Solar Watch?

While both watches are powered by solar energy, the difference is that an atomic solar watch is set by using a radio signal broadcast from the atomic clock at the Forte Collins, National Institute of Standards and Technology located in Colorado. This institute is known to give the most accurate time on earth.

2. Are Atomic Watches Fashionable?

Most solar watches were designed with style and class in mind and are incorporated with leather, gold, and diamonds. They are ideal for outdoor use by athletes and are made of durable materials and also have multiple functions. They are very fashionable as they come in a variety of styles to suit your taste.

3. Does an Atomic Watch Stop Keep Time in the Dark?

No, an atomic watch works both during the day and at night. It features a solar panel that is used to convert light energy into electrical energy and then stored in a rechargeable cell. It’s this rechargeable cell that keeps the watch powered at night.
