Apple Watch's sapphire glass screen IS scratch-proof - even after being DRILLED
comments
Apple CEO Tim Cook described the company's eagerly anticipated watch as 'the most personal device we've ever created'.
And it may be the California-based firm's most durable too.
A sapphire glass screen used in the device has remained scratch-free after being subjected to being rubbed with sandpaper, keyed and even hit with a hammer.

The test was carried out by Cardiff-based iPhone repairs specialist iPhoneFixed.co.uk, which used a sapphire screen from a 38mm Apple Watch for its experiment.

Two out of the three models of Apple Watches, which are available to pre-order from today, have sapphire glass screens.

The glass is made from synthetic sapphire, which is created by applying heat and pressure to aluminium oxide powder, before being processed to remove impurities. Here, it withstands being scratched by sandpaper
The glass is made from synthetic sapphire, which is created by applying heat and pressure to aluminium oxide powder, before the crystals are processed to remove impurities.
The tiny round disks created are ground into shape, and polished, to become glass.
Sapphire glass is said to be twice as tough as normal glass and almost as hard as a diamond.
The regular version, which costs from $549 (£479) and the Edition watch, from $12,000 (£8,000) both have sapphire glass screens, while the cheaper 'Sport' version, costing from $349 (£299) has a strengthened Ion-X glass screen, which iPhoneFixed describes as 'more shatterproof and impact resistant than sapphire glass'.
To test the durability of the screen, it was rubbed against a stone wall and then with a coin, before being 'scratched' by a key.
The video capturing the attempts at destruction, shows no scratches were achieved to the screen.
It also withstood being rubbed with abrasive sandpaper at some force and hit by a hammer – albeit not very hard.

But most impressive, was the screen's ability to withstand an electric drill being dragged across its surface, without leaving a mark.
The test led iPhoneFixed to claim: 'sapphire glass is pretty strong and virtually impossible to scratch'.
Rumours abounded that the iPhone 6 would get a sapphire screen, but it didn't, possibly because the material is expensive to make when compared with standard of tough Gorilla Glass.
