Dear @francois ,
The watchX on this campaign is the same device as in our first campaign. There could be some minor differences in the PCB but nothing that you could see with naked eye. And the features will remain the same.
The main purpose of this campaign is to make the edge connector design of watch available for our customers as soon as possible.
We are working on a more advanced version of the watchX but it will be a different product than the standard version.
So this campaign is basically for our customer who wants to use the full power of watchX and new customers.
