It is said that Apple right now (February 15., 2013) has got 100 product designers and engineers working on a smart watch. Furthermore other rumous state that Apple are doing experiments with curved glass. I'm looking forward to see what Apple pulls out of the hat.
Meanwhile I have modelled and rendered out how I imagine what the iWatch is going to look like. Black metal and rubber. Shiny and matte. Slightly double curved. Enjoy.
