Detecting Continuity number to uniquely identify a watch

[ripvega]

This is an excellent project and works just as described, albeit with the limitation of working with any watch rather than uniquely identifying a watch.

I started to look at this and came across the Bluetooth Inspector app in the Mac App Store.

This shows that the watch emits an Apple Continuity number as below:

This number seems unique and static and is used for communicating between  devices, using AirDrop etc.

Could this be used to identify the watch uniquely?

I don't have the skills (yet) to implement this or to know if it is possible, but unique identification would make a world of difference.
