    YouTube channel Unbox Therapy has shared a new video that tests the stainless steel Apple Watch with a basic diamond tester to determine if it actually has a sapphire crystal display like many regular mechanical watches. The video also tests the Apple Watch Sport, LG G Watch R, iPhone 6 and a Tissot watch that is verified to have a sapphire crystal display.

    The results of the test confirm that the Apple Watch does have a sapphire crystal display as advertised, with the diamond tester recognizing the thermal conductivity of the scratch-resistant material. The verified Tissot watch also displays a reading on the meter, while the Apple Watch Sport, LG G Watch R and iPhone 6 do not yield any results because all three devices have traditional or ion-strengthened glass displays.

    Sapphire crystal is a harder and more scratch resistant material than traditional glass, which is why Apple chose it for the more expensive Apple Watch and Apple Watch Edition display and lenses of the heart rate sensor. Apple cut the sapphire crystal with a diamond-encrusted wire to allow for a precise fit and polished it with diamond-covered pellets for a smooth and glossy finish.
    Apple Watch has been put through a variety of tests since it was released last week, giving users an idea of how the wrist-worn device manages based on both normal and unrealistic usage. CNET shared an Apple Watch torture test on Friday that, among other things, involved submerging the watch in hot water and pouring ketchup and maple syrup on it, while another video took the Apple Watch into the shower and swimming pool as part of a waterproof test.

    I don't think there was ever any doubt about Apple using real sapphire crystal displays. :confused:

    So... was anyone expecting a different outcome?

    It's not like Apple is going to sell something else and label it as sapphire :rolleyes:

    I would have gone with the stainless steel model for the sapphire display if only there were more color options. I went with sport because I liked the space gray color better. The space black stainless steel was nice, but it only comes with the link bracelet putting the minimum price at a thousand dollars. Eff that.

    I think the Unbox Therapy guy is nice and knows his stuff, but my god does he take forever to get to the point in all of his videos. This one in particular could've been 30 seconds.

    "Oh look, it really is Sapphire." ROLL CREDITS.

    No kidding! :rolleyes:

    How about testing something that we don't know yet. Like:

    - What's the battery size in the 42mm????

    - How long does a watch go if you put it into Reserve Mode at 100% battery?

    - Is there a way to fool the wrist detection and move the watch to another arm?

    - Heck, what if you just put a piece of white tape (or a band-aid) under the watch? Does this allow the owner to wear it looser?

    - I.e. Is the detection looking for a pulse? And if so, is that only every ten minutes?


    - etc

    I agree, I love my Tissot! Although I'll probably end up with an Apple Watch v2 or v3.

    Is it a piece of sapphire or just the coating?

    "To ensure a precise fit for the case, the crystal is cut using a diamond-encrusted wire. To make room for an integrated antenna, a tiny groove is laser-ablated around its perimeter. And to create the smoothest possible finish, the crystal is polished with diamond-covered pellets."

    And in the making of this watch, a lot of f***s were given.

    That depends on personal needs. I haven't wear a watch for years and now I'm loving my Apple Watch. Why? I can use the silent alarm to wake up everyday without disturbing everyone else. A mechanical watch failed in this area. Also, with an arm raised, I know the time, temperature, and date. That the 3 things I want to know at any given moment and quickly. A mechanical watch can't fulfill this need either.

    I had no doubts about the sapphire, but still enjoyed the (way too long) video nonetheless.

    The entire display is sapphire. Primary reason why I pre-ordered SS. Unfortunately, I'm first wave and still processing.

    I think apple would have faced a massive class action suit and lost a lot of respect/good will if it wasn't. Its really a no brainer that they used it.

    I don't know about you guys, but I'm getting real tired about hearing about the Apple watch.

    Especially since I ordered it a few minutes after online launch and I still don't know when I'm going to get it :mad:

    All watch news, all the time.

    I guess all the news on all the other Apple things just stopped for a week.

    His old videos were straight to point, the more popular he's become the videos are more long winded, over produced and excruciating to watch


    But who thought Apple was lying? What a pointless video

    Breaking the wrist (connection)

    You can slide the phone quickly from one wrist to another and it will read pulses (and presumably allow for Apple Pay). This has to be done quickly, wrist to wrist.

    If you remove the watch from the wrist, it quickly detects the removal (might be a light sensor) and immediately goes to secure mode, requiring your passcode if you want to do anything else but read the time.

    Don't worry: Ming-Chi Kuo articles will resume shortly, and you will be happy once again.
