I recently purchased this N1F Omega Speedmaster Dark Side Of the Moon. Here are some pictures of it on wrist and in hand.
The dial is very dark as expected. The reflection on the sapphire is noticeable however the hour markers and hands reflect giving it the desired contrast. Date window is sunken but is known about on all models so far. The bezel and case looks nice.
Different angles give different contrasts of darkness. The Crown does not screw down but functions as it should
The stop watch sub dial seems to work just fine, as does the second hand
The Strap feels like it could be a lot better quality but still looks reasonable.
The clasp stays put if put together properly with the strap.
The Rotor is fine
The holes on the strap had to be stretched to receive the clasp prongs
Hope this helps someone
All the best
