Blender Wrist Watch

So I finally got around to moving around in Blender. I started off by using this tutorial on making a watch. That's a screenshot of the rendered model so far. The interface is rather different from what I'm used to in Maya, still with this exercise I feel like I'm slowly starting to get the hang of it.
I'm still not too sure of what I'm doing with the textures and materials. Here are some samples.
