There is an error on Digitec because both are "PRO".
It is more correct to speak about versions WIZ009 (PRO according to digitec) and WIZ017 (not PRO on digitec).
The WIZ017 model has fast charging on the apple watch from the 7 series, the other does not.
I ordered the PRO (WIZ009) from Digitec by mistake without the fast charge... But I can't do anything now...
