This is really coming along great, falloffalot, nice work and excellent render! I particularly like the filligree work in the dial face and hands, and the scale on the smaller dial looks very accurate. One aspect of my job is to engrave on watches such as these, from TAG Heuer and Longines, so I have become a bit of a watch afficionado. Great to see such fine attention to detail, such as the odd convention peculiar to timepieces where the numeral "4" is marked in Roman numerals as "IIII", rather than "IV".
I would like to see a bit more detail in the case itself, with perhaps a joint seam around the outer perimeter, and of course it needs a crown wheel. The inside of the lid is often engraved with fine filligree work and sometimes an inscription, as is the back of the timepiece.
Aside from animation, this model has the potential to produce a really finely detailed still image. Very impressive mate!
