Garmin has introduced its latest GPS smartwatches, and one of them actually features solar charging that'll keep the watch running for quite a bit longer. All of the watches come packed with some pretty cool features for people who like to get out there and go, but the solar charging is definitely the thing that made us stand up and take notice.

Fenix 6X Pro Solar Features

The flagship of Garmin's new Fenix 6 line is the 6X Pro Solar. The watch features a transparent solar lens that will trap energy from the sun and extend the battery life by a bit, which will come in handy for anyone who's looking to spend an extended period of time out in the wilderness without a charger.

Garmin says the watch will last for approximately 21 days when in smartwatch mode, and it can actually squeeze out to three more days of battery life with the solar charging feature.

Outside of the battery life, the Fenix 6X Pro Solar comes with a 1.4-inch display, which is a little bit bigger than the Fenix 5 models.

"We are thrilled to introduce solar charging into the new Fenix 6X Pro Solar edition, giving users all of the features they’ve come to expect from the Fenix lineup with increased battery life and larger displays," said Dan Bartel, Garmin vice president of global consumer sales.

Fenix 6 and Fenix 6X Features

The Fenix 6 and the 6X are similar to the Pro Solar, only they lack the solar charging feature. The 6 comes with a 1.3-inch screen and the 6X features a 1.4-inch display.

Garmin didn't announce any information regarding battery life for the Fenix 6 or 6X.

All of the watches, including the high-end Fenix 6X Pro Solar, share some features including built-in topographic maps, maps of over 2,000 ski resorts and 41,000 golf courses, on-device music storage of up to 2,000 songs, heart-rate monitors that work even while swimming, Garmin Pay, and plenty of other goodies you'd expect to see from a high-end smartwatch.

A really interesting feature that comes with all of the Fenix 6 watches is called Body Battery. It allows you to actually check your body’s energy levels at any given moment, which can help with planning workouts, rest time, and sleep.

Fenix 6, Fenix 6X, Fenix 6X Pro Solar Availability

The Fenix 6 watches are available right now. The base model Fenix 6 starts at $599.99. The Fenix 6X Pro Solar starts at $999.99 and goes up from there depending on chosen options and features.

This isn't the first time Garmin has done something impressive with its smartwatches, as the company also released a crazy expensive watch last year.
