They updated all models (including models previously with 120m) to 30m.
Two questions:
A) is 30m as described, truly Dive watch capable?
B) are older models, equally Dive watch capable?
If it's yes and yes, that's pretty impressive! And finally, a more pragmatic assessment of WR. It's like the WR specification by the PP Seal. 
If no and no, and the 30m is as the ISO standards, then that kinda defeats the uniqueness of several of the models. Could it be a move in preparation for the yet to be launched PP Dive watches?
