hi all
thank you very much for your comments.
I took the watch to tag heuer customer service here in Spain and they are going to send all info to Swizertland to verify it because even the post sales director was not sure about it :-) the only sure thing is watch, movement, crown and bezel are heuer.
Keep you inform about it, maybe we have to include that combination in autavias gallery.
greetings from Spain
Juanjo
