Almost a month after it was reported that Microsoft is planning to offer a sensor-rich smartwatch that measures heart rate, a few more details have emerged about the wearable device. Tom's Hardware reports that the device will have 11 sensors, open APIs, and more, and will be released in October.

The report claims that a "trusted source" has confirmed that the smartwatch will indeed be cross-platform compatible, which means that you'll be able to use it with Windows Phone, iOS or Android devices. This would actually be a good move, as it would open the wearable device up to a larger user base.

The source also confirmed that the display screen will be positioned on the band on the inside of the wearer's wrist. The logic behind the placement is: turning your palm up to look at the watch actually feels a lot more natural.

While it was previously reported that the device will look similar to the Samsung Gear Fit, the new report suggests that the device will have a slim band design, resembling a thinner, flatter version of the Nike Fuelband. The interface is also said to be "pretty slick".

As far as the hardware is concerned, the details are scant. However, the report does reveal that there are 11 sensors under the hood, as well as chips from Atmel, TI and others. When reached out for a comment, a Microsoft spokesperson said, "Microsoft does not comment on rumors or speculation".
