Display specifications

Fenix 7X Sapphire Solar and Enduro 2 are solar watches. Both watches have a Power Sapphire display lens.

Power Sapphire glass is a Sapphire glass coated with a thin layer of Photo-voltaic or PV cells. These photo-voltaic cells help in tapping sunlight to convert solar energy into battery charge.

You will, however, like the nylon loop of Enduro 2. It is softer on the skin and looks better than the default silicone band.


Fenix 7X Sapphire Solar and Enduro 2 offer good battery life. Enduro 2 has a slightly longer backup than Fenix 7X Sapphire Solar. We list the battery backup of both watches in detail below.

The battery backup of Enduro 2 is exceptionally long. However, Fenix 7X Sapphire Solar also offers extended battery backup. It is highly unlikely that you will be left in a precarious situation due to poor battery life with either of these smartwatches.

About Solar charging

Fenix 7X Sapphire Solar and Enduro 2 are shipped with a wire charger. The traditional wire charger remains the primary battery charging source for both watches.

Solar charging is a good secondary source of charging.

For solar charging to add any noticeable impact on battery charging, you will need to spend considerable time under bright sunshine every day.

  • The solar watch needs to be exposed to the bright sunshine of 50000 lumens or higher brightness every day
  • The solar watch needs to be exposed to sunlight for at least 3 hours a day.

Unless you are spending upwards of 3 hours under bright sunlight every day, solar charging will not contribute much to the battery charge on the smartwatch.


Garmin Fenix 7X Saphire Solar costs $899.99 while the Enduro 2 comes at a list price of $1099.99. The difference in cost is $200 between the two watches.

Final verdict

Fenix 7X Sapphire Solar was released in January 2022 and Enduro 2 was released in August 2022.

My money rides on Fenix 7X Sapphire Solar. It offers everything that Enduro 2 does. And, I save $200 on the watch.

The hook and nylon loop of Enduro 2 may be of interest to some people. Barring that exception, I think I am fine with a Fenix 7X Sapphire Solar any time of the day.
