That is pretty impressive if it can really get 8 months on a battery while maintaining a bluetooth connection! Of course, this is quite a different category of product as it doesn't have a screen and just has normal watch hands.

Still, you're asking for an order of magnitude improvement in battery life, so I'll assert again that you'll be waiting a while :) I think you should relax your position, since imo there's really not much difference in having to charge a battery for 30 mins to an hour once a week vs once a month. You still rarely need to worry about your battery, which is qualitatively different than Apple or Android watches that you need to charge once a day or they die on you.
