If it is a genuine original pvd top case then the serials are rarely - if ever - visible. Rather you will need a loupe to see the serials as the coating covers them...

However if it is a repvd case then you will not see the serials as the modern non original pvd process would require the blasting of the case and the serials...if you dont do this you end up with the brushed effect from the stainless steel cases showing. I have both types and have seen several of each in the past year

Cases where the serials are heavily stamped are also i believe non original.

: Since we are on the subject of the black PVD Monacos, let me ask
: the question of whether any readers have ever gotten comfortable
: with the authenticity of one of these that otherwise looks
: genuine, but has no serial number?

: A couple of notes: we all know that the serial numbers on these
: black PVD guys are particularly difficult to see; so that could
: explain the missing numbers there is always the possibility
: that a particular sample was a "prototype", with no
: serial number (but some of us get tired of hearing about these).
: So the question is whether you could ever accept as genuine a
: sample that otherwise looked "right", but the owner /
: seller cannot see a serial number between the lugs?
