Funny you should say that, an old colleague was actually saved by that feature after he slipped on icy steps going out into his backyard. He would’ve froze to death had it not been for a sheriff stopping by for a welfare check. I didn’t know that existed until a few months ago when I read his post on LinkedIn. I was very eager to get Watch 6 but was advised that I should wait for 7. I don’t know how the police or fire services will respond in Japan, but I hope my wife will come out to fetch me.
Also the original ridiculously expensive stainless bracelet on my current Watch 2 saved my wrist in a bike fall 3 years ago.
