Hi guys how its going on?

I have two questions about my Fenix 5X Sapphire

First one is that if its real sapphire because i have some pitting on the glass, not so big but exist

Second one, i tried to install two screen protectors and both didnt glue to the screen, its like the screen dont accept screent protectors.

Have you been capable of installing one?

Not so worried about the pitting because the watch is for my own enjoy and fun on my outside activities, but just for protect it

Real synthetic sapphire will chip and scratch with enough force. The crystal appears to be raised above the case making the edge susceptible to damage. It will be difficult to find an adhesive screen protector that wraps what appears to be an exposed edge.

Thank you so much for your response John, really apreciated

The truth i dont know how those little scratches were made, but im starting to doubt about the veracity when Garmin call Shappire because its really strange all those spots. Look i just made a better photo

About the crystal raised, it is not, bezel is upper than the crystal, i made also a photo

From your pictures, it looks like you already have a screen protector installed on your fenix 5X. Have you owned it since new?

most of sapphire crystals are made out of many tiny grains fused together.
Real monocrystaline sapphire you could find back in the days on expensive watches which now rated at about 15000$ and on rocket heads (guiding things been covered by sapphire). There been few others mission critical applications.
Now it's not the case for mass produced watches and among "artificial", and let face it there no natural sapphire used for watch crystals, there are different grades in terms of hardness and quality.
Despite variations, sapphire is very hard and there is nothing around you capable of scratching it, but it does not mean you can't chip it off. Hard materials are inherently brittle.

If the adhesive from a screen protector isn't sticking to the crystal, it's most likely due to a oil/fingerprint repelling coating (like on iPhones and Apple Watch) or an antireflective coating (like on some watches that have top-side AR). These coatings will make it essentially impossible for any acrylic adhesive used in screen protector products to stick.

If you head over to the official Garmin forums you'll find a few threads with owners complaining about chips and scratches on their Fenix 5x and 6x Sapphire crystals.

That makes so much sense my friend, maybe a big hit made that chips. Im not the original owner and dont know what happened before, but maybe the original owner hit the watch hard somewhere

Thank you my friend

Thank you Ginseng, yeah the watch have oil repelling, i can feel it if i touch the screen with my fingers

So doubt resolved, must be for that . What is a nosense is shops selling glass protectors for that exact model, thats why i asked
