ByShinya Suzuki

Finally from Friday, April 24, 2015 "Apple Watch"Sales started. Apple Watch, which attracted a great deal of attention as Apple's first wearable device, but not only on software but also on hardwareThe idea has been frenziedFor example, it produces a light and tough aluminum body by subjecting aluminum to an oxide film treatment, or manufactures a body that is twice as hard as standard gold by a method established by a metallurgical expert.

Apple - Apple Watch

Among such Apple Watch "Apple Watch" and "Apple Watch Edition" sapphire glass which is more resistant to cracks and scratches than the normal cover glass is used for the display part. The strength of this sapphire glass is considerable, and it can not be hurt even with a hammer or drillAlready demonstratedIt is being done. However,"Apple Watch Sport"Glass of" Ion-X glass "rather than sapphire glass seems to be used for cover glass, so even if you look at the official page of Apple, you do not know except" It's tougher than usual glass " The actual ruggedness remained unknown.

A movie that tested how robust the Ion - X glass used for such Apple Watch Sport is is published on YouTube.

Apple Watch - Will It Scratch? - YouTube


I tested the robustness of the cover glass used for Apple Watch Sport by testing gadgets etc. from a consumer's perspectiveUnbox TherapyLewis Hilsenteger who operates the site called.


It is the ruggedness of the cover glass of Apple Watch Sport that we test this time.


We prepared 38mm and 42mm cover glass, key · knife · sandpaper × 2 · steel wool.


It is the key that there is a possibility that the Apple Watch Sport is likely to crash when putting it in a bag or pocket.


If you scratch with a sharp object like a knife, will the glass part get scratched ...?


Steel wool has fine details3M 10120 Synthetic Steel WoolWhat is used is.


The kind of sandpaper is not revealed, but with fine details ......


Two kinds of rough one are prepared.


That's why I decided to scrape the cover glass scooped with a key at once.


I scratch the coverslip over and over again with the tip of the key like this.



However, glass did not get scratched, in particular.


Although I tried touching with my fingers, it seems that there are no scratches at all.


Even if you change the angle, the glass looks like a shiny new item.


Once again I use my full strength and scratch the glass ... ...


Apparently it seems impossible to scratch the Ion - X glass used for Apple Watch Sport with the key.


Then scratch the cover glass with a knife.


Scratch the glass with scissors at the cutting edge.


However, it seems that it was incompressible to scratch the glass even with a knife.


Lewis also surprised on Ion - X glass which is more robust than I imagined.


Next, I will try to raise the glass with steel wool which made the steel into a fibrous form. Steel wool is a material that can also be used in scratch resistance tests such as metal polishing and lenses and glasses, so if it can withstand this it can be said that it is quite sturdy glass.


Glass after polishing seems to have no scratch at first glance.


I try to change the angle, but scratches are not found on the glass surface at all.


Finally it was time to scrub the cover glass with sandpaper. First of all, rubbing with sandpaper of fine eyes ... ...


Dry the glass with micro fiber cloth.


In particular, scars are not found.


That's why I rubbed it again ... ...


When you tilt the glass, you can see that many fine scratches are attached.


Then scratch the glass surface with rough eyes sandpaper.


Scratching is a brand-new Ion-X glass with no scratches.


Scratching the surface with coarse sandpaper is like this. As expected it is unlikely to have this level of scratch resistance.



As a result of the experiment, the Ion - X glass used for Apple Watch Sport can not be hurt by the fine scratches like keys, knife, steel wool, etc, but if you use sandpaper it will be on the surface of the glass It became clear that it got scratched. Compared to sapphire glass which can not be hurt even by drilling, it seems to be said that the scratch resistance of Ion - X glass is inferior, but rubbing Apple Watch Sport against the wall or carrying it with a sand paper in his pocket If you do not do something like that, it seems that it will not easily hurt the cover glass so easily.
