Fenix 7S Sapphire vs Fenix 7 Sapphire vs Fenix 7X Sapphire Solar smartwatches

We evaluate the three smartwatch models of the Sapphire editon from the Fenix 7 series. Most differences are in terms of the physical size and appearance. The core features remain unchanged on all the three Sapphire watches from the Fenix 7 series.

All the three Sapphire watches have Sapphire glass. Sapphire is the third hardest natural mineral available. It has a hardness between 8-9 Mohs. Watch screen made of the Sapphire glass makes it virtually unscratchable. And, this is the reason that the Sapphire glass watches are considered premium and offer a sturdy look for the wearer.

Fenix 7S Sapphire is the smallest of the three Sapphire edition Fenix 7 watches. Beyond the size, the size of the band and the display resolution of fenix 7S Sapphire are lower than the other two Sapphire variants of the Fenix 7 smartwatch.

  • Fenix 7S Sapphire watch has a physical size of 42 mm, Fenix 7 Sapphire is 47 mm in size. Fenix 7X Sapphire has a size of 51 mm. Fenix 7S Sapphire is ideally suited for thin wrists, while the Fenix 7X Sapphire is a bulky watch that would like nice on broard wrists. Fenix 7 Sapphire is more on the universal size of the watch that would complement most wrists, thin or broad.
  • Fenix 7S Sapphire has a screen size of 30 mm, Fenix 7 Sapphire has a screen size of 33 mm and Fenix 7X Sapphire display screen is a little under 36 mm.
  • Fenix 7S Sapphire comes with a silicon band of 20 mm, Fenix 7 Sapphire has a band of 22 mm and Fenix 7X Sapphire has a silicon band of 26 mm.
  • Fenix 7S Sapphire weighs 58 g, Fenix 7 Sapphire weighs 73 g and Fenix 7X Sapphire weighs 89 g. The size difference can be easily attributed to the bigger size of the Fenix 7X Sapphire edition smartwatch.

Battery life – Fenix 7S Sapphire vs Fenix 7 Sapphire vs Fenis 7X Sapphire Solar

The battery life of the Fenix Sapphire Solar watches depend upon solar charging and the normal charging. For solar charging to be effective in building up charge on the battery, you need to wear the Sapphire edition Fenix 7 watch on a bright sunny day with a luminosity of over 50,000 lux. Fenix 7 Sappphire watches need to be exposed to direct sunlight for at least 3 hours in a day. If you are unable to expose your Garmin Fenix 7 Sapphire Solar to direct sunlight for a minimum of 3 hours a day, solar charging may not add to the battery life of your Sapphire Solar watch.

This also implies that the Sapphire Solar watch may not be the most appropriate smartwatch for people who work indoors. Should you want it for the Sapphire glass’s inherent characteristics, you could definitely get one.

Below, we discuss the battery life of the different Fenix 7 Sapphire Solar watches.

Other Features – Fenix 7S Sapphire vs Fenix 7 Sapphire vs Fenix 7X Sapphire Solar
