Go back and read my "how-to". There are two additional things to do. One is when you are stacking the carbon sheets into your curved mold, is that you want to rotate the sheets at 45 degree angles to each other. That'll give the nice marbling effect on the top. Two, since those layers are so thin, you won't see the zebra stripes on the more pronounced areas of curvature (as you approach the strap). To achieve that zebra effect, you can stack the layers in groups instead of one by one. That way they appear a bit thicker which makes the layers visible to the eye.
Recap with instructions:
1. Roll out NTPT sheet and cut (approximately 6cm)
2. Cut 20 more pieces the same length (estimate here, this will take some experimentation for the right number)
3. Drop into a curved steel mold with all sheets aligned.
4. Cut 19 more pieces and align these as a group
5. Rotate the group 45 degrees and drop into the mold
6. Repeat the process making each layer thinner and thinner
7. Take your mold, apply compression from the top.
8. Drop into an autoclave and bake according to the recommended specs
9. Remove cured block and mill.
How is ABDs process potentially different? You can buy sheets of carbon in all kinds of forms. Some are cheaper than others. As long as they are pre-impregnated with binder, you can mix them up all the same. Just look at the mix of carbon and orange quartz for an example of using blends in your bezel.
