I started with some designs of the clock.
My goal is still to achieve inverted shadows. The designs I did after involved more spheres to smooth the style and create a break with classic clocks.
Though I was quit happy with the sort of metallic clock, I preferred the more traditional look. So I altered the looks, and tried something else which I will try and model.
And this is my maya render.
Still more detail to add on the head of the clock and some more random stuff.
