Thank you all for the help. This is much appreciated. As much as I like the dial and hands, I am a bit skittish about that bezel, as you confirmed I should be. In any case the $10K+ price I think is not justified :(
@Ignace Worang - you could be right indeed with the 79090 hint... it looks like the blue from that reference was a bit lighter - see here for instance:

Thank you everyone for your precious help.
