Today I’m wearing this Christiaan van der Klaauw - Planetarium. I’ve looked for this watch for more than ten years, and this year I found this one!
On the Dutch watch forum, Horlogeforum.nl, I wrote quite an elaborate topic about this watch with lots of background information. I’m thinking about translating it, some adjustments and posting a topic here on OF! Such a special watch imho. 👍
