Something of a closeup here in the car. You can see the outline of my phone case at lower left between the 5 and 8.
It looks pretty cool! I got one question though: what happens to the oil when you got replace the battery?
I don't know yet exactly, but there is a port on the side opposite the crown that opens when 2 screws are removed, and the oil is poured in there. So it looks pretty simple, but only time will tell.
