Go for the Instinct 2X Solar if you want a rugged watch with strong core functionality. The titanium bezel adds a premium look to the watch.

For runners, Forerunner 965 offers the best hardware experience and functionality.


Forerunner 965 and Instinct 2X Solar has multi-frequency positioning sensor. So, both watches support multi-band GPS capability.

Multi-band GPS improves GPS reliability. At any given point in time, you can get GPS signals from multiple satellites. The feature is very useful when the GPS signal is of a degraded quality.

However, Forerunner 965 scores over the Instinct 2X Solar as it has an integrated SatIQ technology sensor. SatIQ is an intelligent smartwatch technology.

Multi-band GPS consumes a lot of battery. To optimize the battery performance, SatIQ controls the switch from simple GPS to multi-band GPS modes automatically.

When the GPS signals are weak, SatIQ turns on the multi-band GPS. And, when the GPS signals are of poor quality, SatIQ will turn off the multi-band GPS.

Combination of multi-band GPS and SatIQ on the Forerunner 965 is a game changing advancement for the GPS performance.

Given the fact that Instinct 2X Solar has an exceptional battery life, the actual battery performance difference is nominal.

In terms of music functionality, Instinct 2X Solar has a limited scope. The device storage of Instinct 2X Solar is quite low and music storage is not available. So, you cannot store music files on the Instinct 2X Solar watch.

But, you can control smartphone music from your Instinct 2X Solar smartwatch.

For the Forerunner 965, complete music functionality has been made available. So, you can get the following music features on a Forerunner 965:

  • Control smartphone music
  • Store music on the watch
  • Play music from the watch

Forerunner 965 is a clear winner when it comes to music features on the smartwatch. Instinct 2X Solar has a limited music feature availability.

Solar functionality

Instinct 2X Solar is a solar watch that can use solar charging to supplement the primary method of charging.

For solar charging to be effective, you need to expose your watch to bright sunshine with a luminosity of 50000 lux or more every day. For optimum battery charging, Garmin recommends 3 hours of solar exposure every day.

Solar charging of the Instinct 2X Solar is pretty useful:

  • if you spend a considerable part of your day under the sun
  • you get decent sunlight all through the day

Solar charging is a supplementary battery charging method for the Instinct 2X Solar. It is a great feature for people who spend time outdoors under the sun.


Forerunner 965 has pretty decent battery life. However, Instinct 2X Solar is designed for basic functionality and preserves battery due to the basic display configuration.

Instinct 2X Solar has a long battery life that gets reinforced through solar charging. The battery backups provided by Forerunner 965 and Instinct 2X Solar are mentioned below in a side-by-side comparison.
