Well-known blogger JerryRigEverything, who likes to test gadgets for strength, has released a new video. It compares the Apple Watch Ultra, Samsung Galaxy Watch 5, and Garmin Fenix 7 Sapphire Solar glasses.
It turned out that the sapphire crystal in the Apple Watch is not as durable as its counterparts. The blogger believes this may be due to impurities in the material or problematic polishing.
On the Mohs scale, sapphire glass must withstand objects with a hardness of 8-9 points, while ordinary tempered glass – is 6 points and above. Test results:
- Apple Watch Ultra – noticeable abrasions at 6-7 levels and severe scratches at 8 points.
- Samsung Galaxy Watch 5 – subtle scuffs at 6-7 levels and severe scratches at 8 points.
- Garmin Fenix 7 Sapphire Solar – severe scratches at 8 points.
The gem detector detected sapphire in all three models. That is, different results are related to impurities in the material and different polishing.
