How about using some isosurface? Your knob reminded me of that in
Isosurface Tutorial (on page
http://www.econym.demon.co.uk/isotut/builtin.htm) and I made few quick
trials. Source and results are below.

I think I've been raytraycing to much these days. I forgot the ambient
and brilliance settings.
Thank you Chris, your comments are of much use.
Alberto.

I think that the last one fits better my needs, but I'm not sure. Thank
you though.

Have a look to the finish settings in my metal textures in the
pov-scene-text-files. They work in most cases. And try brilliance 1.5 or up.
With a bit of work around the textures and the environment (try to add a
skysphere or a box) you'll get a neat image. Did you use radiosity?

Wow. A watch face with no image maps seems difficult. How was it made? Is
it made of cylinders, boxes placed with macros and text rotated so it faces
up? How about a chain or little dials? It would be cool to make a
grandfather clock with a dial that tells the phrases of the Moon. Maybe it
could use include files to render a clock set to the current time. I jump
between many projects and never get them done! :)

I can't speak for Alberto, but for the animation that Josh and I did for the
IRTC I made a 3D clock face. Opposite of the stopwatch though, we turned
that into an imagemap for what we needed to do with it. Pic and code is
below if you are interested. A previous version of this used paper thin
boxes instead of cylinders capped with spheres, but I wanted a more 3-D
effect than what I had in the first round.

I set the brilliance to 1.5 and ambient to 0 and I'm on track now.

No I didn't.
Thank you for your help.
Alberto.

Interesting but: the .pov file should be posted in one of the scene file
groups and the .bmp should have been something much smaller like a jpg of
that image would come out at a few K rather than the 225k bmp that you
posted.
There are reasons for my suggestions and they are described well in the
welcome message in the group povray.announce.frequently-asked-questions.

Well, the max_extent command was very handy to place the text. I used
the onion pattern to make the black circles and little boxes for the
hour-minute marks.
I don't think I'll do any more developments with this watch, as I feel
its a finished work. I'll post an image with the little changes in
ambient and brilliance settings.
I'm planing to send this and other two or three images to the 10best
project, but I still need some time.
Regards, Alberto.
