OnePlus Watch Unboxing and First Impressions Smart Wearable Like Samsung Gear S2 or Apple Watch

Unboxing of the new One Plus Watch. As with most OnePlus products like their phones and audio, the Watch is intended to be a straightforward wearable focused on the health logging benefit of smart wearables. I expect regular updates to the software adding additional functionality. The size is larger than a Samsung Gear S2. We will be doing some side by side comparisons over the next week looking at overall battery use, recharge rates, and comparing the data from both watches.
