Czapek California Blue 41, 5 mm Steel case LE 18 Pieces.
Not a novelty, but one which made some good impressions on me. No date and a manual winding movement and I would have jumped on it. Best, Nicolas ...

That is a sweet looking watch!
Thank you, Hermano as I did not know about this version. Cheers, Alex
