At first I tried to achieve the brushed aluminum/gold look for the metal body thru procedural textures only but that quickly fell apart. Instead I used an anisotropic shader and turned to Photoshop image-based textures for color, spec, and bump for all the metal bits. The face in particular relied on bump and spec maps to shape the number cutouts and reflective materials. The band too used color and bump maps for texture and a spec map to "knockout" the perforations in the reliefs. Read Less
