Best Atomic Solar Watch Buying Guide
Atomic watches aren’t cheap. There’s a suitable atomic watch for each of us, some like digital display while some prefer analogue. You also need to consider the battery performance, construction and additional features. Here’s what you need to know while purchasing an atomic solar watch.
1. Battery Life
The most important thing of all, is the battery life and its charging time. As we all know, atomic solar watches are charred either by solar energy or by artificial light upon their exposure. Therefore, keeping the watch working along with all its features. Nothing is more frustrating than your watch taking the entire time for a recharge. If kept under the sun a potential solar watch can take a few minutes to a few hours to get fully charged whereas artificial light can take hours for a full recharge. You need to check the user guide to know about the exact timing of a recharge. Thankfully, most atomic solar watches have a better battery life than can last anywhere from 2 to 10 months. Each time you go out in the sun or your watch gets exposed to any source of light, it charges the battery, extending its life and working time.
2. Additional Features
Additional features that come with atomic watches and whether to consider them or not depend on your purpose of use. If you are a sports person and your watch must go through extreme wear and tear, you need to look for water and impact-resistant watches. Most of our watches, especially the Casio series, are upto 200 m water resistant. Other basic features that most watches have include stopwatches, countdown timers, alarms, etc. If your watch is for everyday use, make sure it displays the date and year and is backlit for nighttime viewing.
3. Material
Like most watches, atomic watches are made from stainless steel, plastic, resin, and titanium. The dial case might be made of steel, but the straps may feature a raisin or leather belt. Or the entire body can be made of stainless steel, titanium, or plastic. There’s nothing that’s good or bad. It all depends on your comfort, But it’s better to stay away from cheap plastic materials. Leather belts look great if you wish to wear them as a dress watch. But do not compromise on the quality if you are a heavy user. Another thing that you need to make sure of is that the screen is made of durable mineral glass, as plastic is prone to scratches.
4. Daytime Light Saving
This is one of the important factors, and thankfully most solar-powered atomic watches come with this feature. Daytime light saving automatically saves power and reserves battery life. Solar-powered watches can extend their battery life with daytime light-saving features that can last for years without a recharge. It is important to conserve your battery life especially when you’re out on an adventure.
5. Analog or Digital
When you are buying a solar atomic watch, you get two options, digital and analog. However, some of them are hybrid atomic watches, a combination of both analogue and digital. In most cases, digital atomic watches are preferable because of the features they come with. The features are worth investing in, especially if you are a serious outgoer. With a digital watch, you might expect additional advanced features like GPS, health monitoring, wireless connection, weather report, environmental sensors, timer, alarm, stopwatch, and many more. In the case of analog watches, you only get to see the time, date, month, and year. Though the functions are limited, analogue atomic watches make great dress watches. So we recommend you buy a hybrid watch which has the hands of an analogue watch with a digital display.
6. Size
The size and design are probably the second things you need to consider. It decides comfort, weight, and convenience. The standard watch size can be anywhere between 42 to 56mm. This varies widely, but you need to decide according to your convenience. Bigger dials are easy to read and operate. But most of them are heavyweight. But do you have a wrist big enough for it? Make sure your watch fits you well, as you are going to wear it for a good time.
7. Purpose
The purpose is another thing to take into account while purchasing a solar atomic watch as there are different watches suitable for different situations. For example, digital solar atomic watches featuring a digital compass, barometer, and altimeter are more suitable for people like military personnel, law enforcement officials, etc. If you are a frequent traveler, you would appreciate a watch that has a GPS tracker, environmental sensors, and a rubber or silicone strap that can be worn for 24/7 hours.
Conclusion
If you insist on accurate timing, an atomic watch is for you. If you want to get rid of replacing your batteries or charging them every while, a solar-powered one is your best bet. Together, the solar atomic watches make the best kinds of watches that you can buy. Spend some more for better quality, materials, and a brand that offers reliable customer service. It will be beneficial in the long run. Make sure your watch includes basic features like a stopwatch, countdown timer, and alarm, if possible. But, be mindful while spending extra pennies for the feature. Do you need a GPS? Do you need weather updates? Is health monitoring really important for you? So, what solar atomic watch are you buying? Are you still confused? Here are our top three recommendations:
If you are looking for a budget sport atomic watch, then Casio G-Shock GWM5610-1 is your best bet.
