Thanks,

I have checked this. Interesting enough my watch has a glossy blue dial with the subdials in a somewhat darker blue. The dial colour is the same as on the blue cal15 Monaco.
I just showed a photo (by e-mail) to an ex-Heuer watchmaker. He just wrote back that he thinks its authentic and that he can remember Monacos without applied markers but these printed markers.
Would like to send the photo to the forum, but how to do that?
