Me as well, I have a drawer of watches and I want to use one but the 1-2 day battery life is just a dealbreaker .. 30 days will probably make me care to put it on again after the charge is done.
I've heard some people say that newer AWs can last indefinitely if you charge only while in the shower. That could be good enough. But I still don't want to have to bring another charge cable with me every time I take a trip. One week is good. Two weeks is great. A month is amazing (partly because after the battery degrades for years, it will still be two weeks).
