It’s Complicated…
The Christiaan van den Klaauw RealMoon 1980. Beautiful and mad at the same time… It’s too nutty to describe myself, so here is an explanation of it’ s complications from the CWDK website…
“At the six o’clock position on the dial of the watch, a true-to-life ‘miniature’ Moon depicts its actual phases. At the 12 o’clock position, the height of the Sun in relation to the horizon can be read by means of a fine moving Christiaan van der Klaauw logo. The axis of the Earth’s rotation is tilted with respect to the position of the Sun. The result of this phenomenon - called declination - is that at places where the Earth is tilted towards the Sun, it is summer. Where it is winter, the Earth is tilted away from the Sun, and it is colder. The three o’clock position is reserved for the so-called Eclipse hand. When the Eclipse hand moves within the indication marks, there is an eclipse of the Sun or the Moon somewhere on the Earth. Finally, there is the nine o’clock position. Here, the phase of the Moon and the date can be seen.”
