1. Garmin Instinct Solar – Best Overall 

1. Garmin Instinct Solar – Best ABC Watch Overall 

The Garmin Solar Instinct has an updated heart rate sensor and a significantly increased battery life even without solar charging. If you add the solar power option, too, you will get the best battery timing that any Garmin watch has yet to offer. 

Disabling specific sensors and turning this only into a watch will give you 56 days of battery life, which is unlimited. Not only this, but The Garmin Instinct Solar also now sports a blood oxygen saturation monitor.

After thorough testing, we have a lot to share with you about the Garmin Instinct Solar. When it comes to the variations, this comes in three different editions. 

You have the camo version that has a camo case, and then you have the surf edition. This one has tide data as well as a surf-specific profile. You also have a tactical version with night vision, stealth mode, and a jumpmaster profile.

The first thing you might notice is the new little chart on the watch face that shows the solar exposure the watch has had over the last six hours. 

Hidden underneath that is the solar panel with a ten photovoltaic level. However, the real magic comes from these reflective bits surrounding the display. These solar panels get a full hundred percent photovoltaic level.

The Instinct Solar might have a black and white display, but you will notice that this is the easiest-to-read display out there. Especially in direct sunlight. 

It comes with a wide variety of sports profiles and plenty of gym-based profiles too. The GPS performance will do everything well and leave you with zero complaints. 


  • Unlimited battery life.
  • The heart rate sensor works well.
  • Modern and sleek design.
  • 3 different versions.
  • Multiple sports profiles.


  • The altimeter can be more accurate.

2. Suunto Core – Best Budget ABC Watch

2. Suunto Core – Best budget ABC Watch 

The Suunto Core is an all-black military watch with a negative dial. This watch is neither heavy nor bulky. Even though this is on the larger watch size, you will have a very slim and lightweight profile. 

Even though it’s supposed to be a tactical watch, it sometimes gets challenging to read the dial because of its negative dial feature.

With a reverse display, it is a bit challenging to see, especially in low lighting. You need to get the angle right with light reflecting on it to know the time. 

If you are still reading, that means you have gotten past the visibility issue! 

So, let’s have a look at some of its more interesting features. It has a rotating bezel and checkered buttons at its side. 

These control the altimeter, barometer, and compass. The watch band itself is super flexible and soft. The Suunto Core has been on the market for a couple of years and is so far a really good option for people who want something low-budget and easy to use. 


  • Easy to use. 
  • Sleek and Slim Different color options.
  • Durable.


  • Limited visibility.
  • Only has essential functions.

The company advertises a 60-hr battery life in a normal GPS mode and a 150-hr. battery timing in an ultra-GPS mode. If you look at this and some of the other features, you might find this a replica of the Garmin minus the more advanced features. 

Talking about the things you will most probably like about this, the battery life tops the list. This watch’s battery life is phenomenal, beyond comprehension. 

In 23 days of running 5- 6 days a week, this will only come down to a 4% at full GPS accuracy. So, you will not have to charge every other day. But, once it goes below the 10 percent mark, you will not like the experience. 

The simplicity in the user experience is unmatched, and it lets you do all that you want without any complex steps. 

Moving on, the COROS Vertix has straightforward and customizable software too. Updates are quick and set on auto. The app may be limiting but provides you with the basics you might need. Overall, this device offers consistency and is constantly working towards the better.

Like the Garmin Instinct Solar, this too has solar power charging. The Fenix 6S pro has a hundred percent solar efficiency around the edges but a 10 percent efficiency in the rest of the display. 

It might not be designed to power your watch indefinitely, but it comes pretty close in some scenarios. Turn off the sensors you don’t need at the moment and turn this into a regular watch, and you will end up getting a dramatic increase in your battery life.

Another fantastic feature is that it syncs all the data it receives from active GPS users and highlights the most used and trending hike routes for you. Now, this is an amazing feature but shows accurate data up to only a mile.

  • 2000 Preloaded Ski maps. 
  • Music streaming.
