Not black, not white, not light etching. The monaco 24 that hit the market has no lettering at all! I just found out this review (http://www.calibre11.com/review-monaco-24/), according to which the differences between the prototype and the production model are:
" ... limited to:
* Production watch is Stainless Steel, coated with black titanium-carbide- the Concept 24 was Tungsten (note- in an earlier post, I’ve described the case as Titanium with a PVD coating- this is incorrect)
* Production 24 loses the “TAG Heuer†script from the bottom edge of the case
* Although you can’t see it in these photos, the Production 24 has silver bolts along the side rather than black."
