Christiaan Van Der Klaauw is a Dutch independent specializing in astronomical automatons and time pieces. They have been around for a while. They don’t get much love (not Swiss or German) and not enough people know about them. I’m not sure why that’s the case. This is their simplest watch in terms of movement, but I always liked the overall execution. I’ve swapped out their deployment band for something a bit more exotic as I wanted a bit of fun.
The 12 o’clock Sun is normally blued steel and I had them make mine gold (easier to see in a dark room).
