Confused about Monza crown

I have bought a vintage PVD Monza which is in good condition but has what could be a replacement crown as it does not have a Heuer logo. I was about to start the search for a replacement but as I looked at lots of online images it seems that many appear with non branded crowns like mine.
Can anyone throw any light on this please?
If I do need to replace does anyone know a reliable source and fair market price.


Thanks for your help

Can you upload a photo of said watch. 😀

There you go
Many thanks

Hi Roger
Did you get any resolution to this question?

I too have seen many with unsigned crown and wonder why. I have read somewhere about this being an Economy model and why it has the Cal 15 rather than Cal 12. Not sure that is correct though.

Apparently an unsigned crown is the real deal
Cheers
