[Lucidor]

Interesting - I have one similar to yours. Is this one experimental as well?

 

[Gravit]

Experimental or not Lucidor, I love your Cornavin.

 

[Mark Gordon]

Yes, Lucidor, I have a Cornavin with the same movement, as well, but in a different case.
Seems to me that this movement was produced in quantity for both the domestic and export markets.
