Yes.
Although I'm not going to buy it, since I don't feel the need to take pictures with Watch, it is good to see new bands with additional functionalities. They can communicate via bluetooth and that's ok, the only downsize is that you have to charge the band and it is quite inconvenient. I see they sell an accessory to charge Watch and the band at the same time, but I assume it would only work with their band.
It would be great to have a set of bands sharing the same charging system, so you can have pictures, health monitoring and other functionalities embedded into different bands, but being able to charge all of them with a single charger.
