Yes it is 256016 to 256486 is the range, your new addition i make the 8th on my register with three known with original dials/hands but with a RE PVD case also, so serials not an option...

I'm not sure in my mind if they wee ever sold or a prototype/trial run? Difficult to know for sure, there do seem to be conflicting stories on OTD about this issue,if you search the past posts on the forum.

: I was after this one for quite a time now, interesting is
: that the serial numbers on the pvds seem to be all 2560xx and
: 2563xx.
: Does somebody own one with serial numbers in between ?
: I guess we have encountered so far around 10 watches resourfacing,
: half in new old stock condition, which would lead to the
: conclusion that the black Monaco did not sell well ?!
