Thanks for the challenge, Thomas. Here is my try:
1. Different colours of the subdials (minute counter has another colour than permanent second), shape of the hands, frame for the date loupe, subdials and date loupe seem to be attached to the seconds scale ring (rehaut), different material of crown/push-button protector than the rest of the case
2. motor racing: subdials look like instruments, dial pattern like a grill, the slanted square grooves con be associated with (hood) scoops (to allow additional fresh air to flow directly to the engine or to the breaks), the crown looks like a wheel with spokes
3. Hard to find an asociation for the colour combination, Schumacher would not be bad (black, red and gold for the colurs of the german flag) but he has a contract with Omega, perhaps Barichello IV (okay that is not very creative)
4. my guess is magnesium (the surface of crown guards reminds me of this material) and forged carbon, other combination could be rose gold and forged carbon
5. 3-dimensionality or sculptural design as seen on the dial (not only the red dial itself but also the way the subdials and the loupe seem to be attached to the seconds scale and seem to leviate above the red dial) and disaggregation: Each prt of the watch is separated from the other parts (i.e. crownguards have other material than the case and again the elements of the dial), the constructive elements are somehow naked and highly visible like the screws of the crown guards. This reminds me of the Centre Pompidou in Paris click here with its visible tubes for the air conditioning and pibes for the moving stairs or similar the Lloyd's Building in London click here
Cheers,
Christoph
