We've long known that Microsoft is working on a smart watch device, but we had no idea what to expect when it comes to design or features. Now, due to a patent filed by the software company back in 2012, and grant this week, this smart watch could turn out to be something special.

The diagrams show that this device will rely a lot on sensors that are designed to read heart rates among other things. Not surprising, because almost every current and future smart watch we know of are designed with reading the user's heart rate in mind. The big problem is current devices have failed to work properly, which makes us have less hope for the future.

Interestingly enough, it appears Microsoft will allow the ability to change the wristbands. The band itself is separate for the computing section of the smart watch. With a press of the button, both can be separated, which makes us wonder if Microsoft is aiming for something that is fashionable where users can choose different color wristbands.

This could be a splendid idea if it does come to fruition. Instead of having to purchase another Microsoft smart watch to get a hold of that color you've always wanted, just purchase the wristband itself. It allows for customization and cash savings.

Like the Samsung Galaxy Gear, this device from Microsoft appears to be charged via a dock, which also functions as a stand. We envision many persons using to the dock to stand their smart watch on their desk at work or the office at home.

We're not sure of the software Microsoft plans to implement in this smart watch, but chances are it could be a version of Windows 8. Back at the company's Build 2014 event, an initiative called Windows on Devices was shown off, it is a Windows software designed for smart devices such as watches and in-car radio.

An altered version of this software could do wonders on a smart watch device, but that's if Microsoft doesn't screw it up first.

We don't expect Microsoft travel this route alone. We believe the company might release the first smart watch device to give partners an idea of how to move forward before opening the floodgates. Then again, it is also possible for Microsoft to travel this road by its lonesome since it now owns Nokia's hardware business, thus meaning Microsoft now has the power to become the next Apple.
