Matrix Powerwatch

The Matrix Powerwatch can go days and sometimes weeks without charging. This is done with Martix industries unique charging tech, charging the watch via body heat.

When left idle, the Martix Powerwatch will automatically shut down and that conserves battery, although not indefinitely.

Pros:

• Unique, you would never have to find a charging port again.

Cons:

• Its expensive. at about 200USD, I would prefer to pay a bit more for other smartwatches in the market.
• Its huge. Great for guys but not that suitable for the ladies.
• Limited software.

Overall, there is huge potential for the matrix's technology and this will hopefully be refined over the years.
