Thanks a lot for pointing them out to me.
In a comment below, Carlos22 also pointed out the Roger Dubuis Bulletin d'Observatoire, which are interesting pieces as well.
But what I was specifically looking after was this particular dial layout with small seconds at 9 o'clock and the observatory mentions presented as a second subdial at 3 o'clock...
I'll keep in mind the Rolex and Dubuis for another post!
Best, Emmanuel
