A member at the Windows Central forums posted a few images of the Microsoft Band 3 prototype. The user also claims that the wearable would have featured blood pressure tracking, waterproof design, and support for RFID. The images seem authentic and show a fitness tracker similar to the Band 2, but with slightly improved clasp. One of the images also reveals a swim tile, which suggests the device is waterproof and user would have been able to use it to track swimming sessions. And then a second tile that shows the ability to track blood pressure data. Microsoft recently discontinued its second version of the fitness tracker, but never officially revealed the reasons for the decision. However, the company said that will continue supporting customers who have purchased the wearable. Update, October 2016: Here are a few new images showing more details on the canceled Microsoft Band 3.
