Solar smartwatches and watches are a better alternative to traditional watches as these watches can be charged using solar or artificial light. And that’s also a reason why solar watches tend to last longer than traditional watches as they don’t need battery replacement every year or two.

Opening your watch just for replacing its battery can compromise its integrity. Improperly sealed watch by your jeweler can also jeopardize the waterproofing capabilities of the watch. We all know too well the pain of losing the watch that you have been wearing for the past several years.

For all these reasons alone solar watches are perfect but finding a good and reliable watch at a reasonable price is no easy task. Keeping all your requirements for style, durability, taste, and budget we have shortlisted 7 best solar watches under $100 that you can buy.

Buying Guide For Best Cheap Solar Watches Under $100

1. Solar And Fluorescent Charging

Some solar watches can also be charged using fluorescent lighting. However, it won’t be okay to rely only on fluorescent charging as it is very slow compared to Solar charging. Fluorescent charging is a nifty feature to have but don’t expect your watch to be fully charged solely using fluorescent charging.

So if the watch you have selected doesn’t have fluorescent charging that doesn’t mean you are missing out on a very crucial feature as solar charging is more efficient and reliable than the other.

2. Battery Reserve

When you place your watch under the sun, it stores all the energy into the watch’s battery. Once the battery is charged, the watch will use energy from the battery whenever you aren’t under the sun.

Therefore it is important to see how much battery backup your solar watch will give you on a single charge. It can be as high as 10 months to as low as 2 months so if you think charging your watch every 2 months can be a hassle for you then go with another one.

3. Durability And Water Resistance

Not all watches are durable enough for day-to-day usage. For instance, some watches feature a nylon strap which can get worn out with daily use. Then there are watches with stainless steel straps which are durable but not lightweight enough for some users.

Some watches are only waterproof till 30m meaning they are splash-proof at best and would require some extra aftercare. However, G-Shock Black Resin is water-resistant up to 200m and therefore won’t require any aftercare.

Hence, if you are in a profession that requires working with tools then go with G-Shock or Casio otherwise go with any casual or dress watch.

4. Warranty And Brand Name

If you are spending your hard-earned money on the watch make sure to check whether or not the watch comes with a manufacturer warranty. You might face a situation where you notice a manufacturing defect after the return period is over. So buyers be aware!

Also, check whether the watch is from a good brand or not, so at least you would be able to reach out to customer care if anything goes wrong with your watch.
