Pretty sparse info...
the video and write up was interesting but hardly informative...
too bad about the limited functionality of the watch..
but it was yet to be released...
so I would imagine ..had it been released ..more functions would have become available over time...

Yet again I suggest tracking down those who worked on the Moonraker...
they will have a great deal more that would be helpful for your predicament...

The only other thing I can suggest is...
Have you ever used any nokia BT peripherals before?
look at all other nokia BT peripherals ...
they seem to follow a standard method for pairing ..
perhaps they did not deviate from their norm.
Best I can personally suggest...
