I removed Battery Monitor cause when I check it in glance sometime my watch reboot...
It happened twice...
I'm still at WatchOS 1.0 on my watch so can't tell if "Battery Monitor" is ok with 1.0.1 ?
So I found 2 other Apps and I'm testing them and let you know if they are ok.

I use MacID to unlock my Mac and the Watch app shows the iPhone battery life.
I installed Battery Monitor right after I saw your initial post about it. I'm on 1.0.1 and have not had a single crash.I removed Battery Monitor cause when I check it in glance sometime my watch reboot...

I just added it to my watch face. I was using the chronograph face with the health monitor in the bottom left by default. I held the watch face, tapped customize, and then tapped the health icon. Then, I was able to dial down to the battery-level display.
