The hours are indicated in Roman numerals: I, II, III, IIII, V, ... XII. The minutes are blank, 5, 10, 15, ... 55.

The 1815 Moonphase seems to have a different type of HG as compared with the 1815 200th Anniversary and new 1815 Thin: over time, the earlier HG turns closer to yellow gold, whereas the latter models seem to maintain their paleness.

I don't know for sure, but maybe since 1:51 ("ten to two") looks more balanced on the Lange 1?

Perhaps the dial guilloché is being reflected on the mirror-polished underside of the minute hand, and that's what's visible on the XII index?

The blue hands increases legibility! I also noticed that yours says "Kiev" where mine (a normal TZ) says "Cairo".
