What is the difference in the firmware the FAW 1.1 verse the 1.4

I would like to thank you for the help on the firmware update on my prime to watch. Now the question is what is the difference between the two new versions The V1.1 to the V1.4. and do I need the V1.4

You will find all the difference here, in the first post:

How can I tell if I have the D09 model prime to watch.

If you have a prime 2 thats got its original firmware you can upgrade to faw its way better and gives you the functions your phone has except no nfc.
