The Five Best Solar Atomic Watches – The Best Way to Keep Time Across the Globe

Have you ever asked someone for the time and more than one person answers with a different answer from the first?  Even if the times are a minute or two apart from each other, who’s watch do you believe?  And why do they differ so much?

The reason they differ in time is that chances are, they are battery ran watches.  The battery run watches are set by the person owning them.  Solar atomic watches are controlled by radio.  This means they are much more accurate than battery-powered watches.

Solar-powered watches keep the best time across the globe as they are the most accurate.  These watches will remain in sync with the US Atomic Clock, which is located in Colorado.  Every evening, all solar powered atomic watches will receive a low-frequency radio signal.

Five Best Solar Atomic Watches Product Reviews

1.    G-Shock Rangeman GW-9400- The Best Overall

Being able to know the exact time can be a challenge unless you have a great solar atomic watch.  G-Shock Rangeman GW-9400 can help you in always knowing the exact time so you are never late. Known as being some of the strongest and most durable watches in the industry, G-Shock Rangeman has been worn by police officers, military, surfers, skiers, campers, hikers, and many more! 

The G-Shock Rangeman GW-9400 is our best overall pick because it is feature-rich!  We love the digital compass, altimeter, barometer, and thermometer, as well as the time stamp.  The best feature by far is the sunrise and sunset date.  Other great features include Mb6 atomic timekeeping, auto LED, 5 Daily Alarms (4 one-time and 1 snooze alarm), 1/10-second stopwatch, countdown timer, day/date/month calendar, and buckle closure.  As it has a protective crystal mineral dial window, you will find this watch to be scratch resistant.

All of the sensor buttons feature their own tone.  I find this is nice as I can be busy doing something else while looking for the right sensor that I want based on the tone I hear.    I also appreciate the beauty of the watch.  The black resign band looks amazing against the red accents on the dial. 

If you love to scuba dive, this watch is water-resistant to 660 feet!  There is a  mud resistant case and buttons that are well-sealed so no dirt, mud, or debris get into the watch. 

All in all, I would highly recommend the G-Shock Rangeman GW-9400 to anyone that is looking for an atomic watch with lots of features.  For the price tag of this watch, the features definitely match up with it.  While the thermometer may not always read accurately, it is a simple fix to take the watch off and wait a few minutes to tell the correct temperature.

Pros

  • Requires very little maintenance
  • Has a triple sensor with a direct access button
  • Consistent updates
  • Super easy to read
  • Shock resistant

Cons

  • The thermometer does not always read accurately as it reads your body temperature too

The Ultimate Buying Guide to the Best Solar Atomic Watch

Here we have compiled a comprehensive buyer’s guide for the best solar atomic watches.  We will go over the features that various solar atomic watches have, things you may wish to consider, as well as frequently asked questions. 

Features to Consider

Solar atomic watches come with various features.  Here are some that you may consider.

  1. Shock resistance:  This feature is suited for analog watches.  With sudden movements, a watch can be damaged.  With the help of shock resistance, you do not need to worry about moving as much.
  2. Time zones:  Solar atomic watches cover various cities.  It is in your best interest to pick a watch that covers as many cities as it can. 
  3. Battery life:  Aim to purchase a watch that has long battery life.
  4. Accuracy:  Look for a watch that is as accurate as possible on the time.
  5. Display:  This feature is important as you want to be sure you can read the watch.  Some displays feature larger numbers than others.  Pick a watch that has a display that you are comfortable with.
  6. Functions:  There are extra functions that many solar atomic watches come with.  These may include a compass, temperature reading, backlight, alarms, stopwatch, and a barometer.  Others will include an altimeter to show the altitude of your location.   Hikers and campers may find functions, such as a GPS finder, come in handy.

Things to Contemplate

The following are all things that you should think about before purchasing a solar analog atomic watch.

  1. The brand-  This can play a huge role in which watch you will pick for yourself.  Individuals that purchase solar-powered analog watches from classic brands, such as Casio, are much more likely to be satisfied than those that purchase a generic or knock-off-brand. The more well known a brand is, the higher the likelihood that quality materials are used.
  2. The price- Many people want to purchase a watch that is not super expensive.  They do not want to pay an arm and a leg for one. However, one should always follow the old adage of you get what you pay for.  There are many brands that make solar watches that fit in all budgets.  Some are under $100 while others are well above $500. If you are looking at a watch that is $20, you are most likely not going to get a high-quality product.
  3. The weight- One thing to consider when purchasing any watch is the weight.  Your comfort will determine if you like wearing the watch or not.  Heavy watches will most likely not be as comfortable as a lighter weight watch. 
  4. The feel-  Once you have the watch on, how does it feel?  Does it cut into your wrists?  Do you like the texture against your skin?  Is it comfortable?  All of these should be answered in order to fully determine if you like how it feels on your wrist. If the watch is steel but is too large, you can ask a jeweler to cut a section out to fit your wrist properly.  Other materials, such as leather, are generally used with some sort of buckle.  This can easily be adjusted.  Typically, the two types of closures are either a buckle or a clasp. 
  5. The design- Solar-powered atomic watches come in many designs and styles.  Some are in standard colors while others are brightly colored.  Others are sleek and sophisticated.  Many look like an aviator style watch.  The style and design you pick are important because it will decide itself when it is appropriate to wear it.  An example of this is if you have a business meeting, you most likely would not want to wear a sporty watch.  Rather, one that is elegant looking would be a better choice.
  6. Materials- You should look at what materials your watch is made from.  Stainless steel and resin are both popular choices when it comes to these watches because they are both durable.  Others are made from nylon or leather.  There is not a right or wrong choice when it comes to materials as it is a personal preference.
  7. Ease of use- Is the watch easy for you to put on yourself?  If not, will you always have someone there to assist you in putting it on?  If you can not get it on or off by yourself and have no one to help you with either of these tasks, it may be wise to look at a different watch.
  8. Customer service:  Customer service is extremely important when it comes to purchasing anything.  A brand is only as good as their customer service is.  While researching brands, it is wise to look at brands that customers have been happy with how their issues were resolved.

The Best Solar Atomic Watches FAQ

What is a solar-powered atomic watch?

A solar atomic watch is a radio-controlled watch that searches at least once per day for the 60kHz radio signal in order to decode the correct time.

Are solar atomic watches reliable?

Yes, solar-powered atomic watches are very reliable.  In fact, they are more reliable than a watch you have to set yourself.  Each day, the watch receives the radio signal to be certain the watch reads the correct time. 

Are waterproof and water-resistant watches the same?

Waterproof and water-resistant are two different things.  A waterproof watch can be submerged in water completely.  Doing so will not result in any malfunction.  A water-resistant watch can not be submerged or they will malfunction.

Why should I own a solar analog watch?

Solar-powered analog watches are a great investment.  There is barely any maintenance with them.  You will never have to set them yourself, nor will you have to pay to have a battery replaced.  If you travel frequently, they are a necessity as you do not need to figure out the time difference once you arrive at your destination. 

Another reason to own a solar watch is if you are active in water sports, camping, or other nature activities.  These watches are perfect for beachwear, scuba diving, swimming laps in a pool, or surfing.  If you find a watch with a compass, it could come in handy when you are camping or hiking.
