To be fair I find it useful if you keep a load of watches in the box to half wind it when you're picking it up to use it after it's stopped for a while, or to keep certain watches running whilst sat in a collection. It's a quirky little complication I like. Is it essential? Definitely not.
I find it useful to see the state of charge, I understand that you have an opinion, nothing wrong with that.

Mine has arrived with no theft and a really useful power reserve dial.
In the post you are replying to, I have explained why IMHO I feel a Power reserve on a 40Hr reserve Auto is pointless, albeit you have edited out that part, which is the part that answers the question you have asked. (confused)
