Modelling

Simplistic, black rim

I have created some more faces for the clock and also played a bit with the color and material of the rim.

Hour marks only, red plastic ring

The second also isn't bad. The red plastic material is a bit bright, though.

Four marks with numbers, brass rim

Then I tried brass for the ring. It is showing a problem with the model, the segments start to show. Perhaps an area light would help. Also the marks are too big when used together with the numbers. That is true for all the following faces.

Hour marks, for numbers and back to gray rim

Next I used twelve marks and four numbers. I also returned to a gray rim. The numbers look too small, but actually the marks are too big. I think this could look quite good with smaller tick marks. I will probably try that.

Minutes are marked, all 12 hours with number, still gray rim

And finally with hours and minutes marked and the twelve numbers.
