If your Garmin's name includes Sapphire, a protector is optional. If not, it has Gorilla Glass, which scratches more easily outdoors, so fit round tempered glass cut for your exact model and size.
Sapphire or Gorilla Glass?
Garmin sells many models, including Fenix, Epix, Forerunner and Instinct lines, in standard and Sapphire editions. The edition is in the product name on the box and on Garmin's site. Sapphire lenses are far more scratch-resistant; standard Gorilla Glass lenses pick up marks from rock, sand and gym equipment.
| Lens | Scratches | Protector |
|---|---|---|
| Sapphire edition | Very scratch-resistant | Optional |
| Standard edition (Gorilla Glass) | Scratches more easily | Recommended for outdoor use |
Sizing
Garmin protectors are sold by model and case size, for example 47 mm vs 51 mm. Round glass must match the visible lens diameter exactly, or it lifts against the bezel. Many packs include several pieces, which is handy on a watch used for trail running or climbing.
Solar models
On solar-charging Garmins, the solar ring sits under the lens around the display edge. Clear, thin glass has little effect, but avoid tinted or matte protectors, which can reduce how much light reaches the ring.
