The Cubitus, really, is a test. It's here to check your design litteracy. To a simpleton, it's just a big ugly square that kinda looks like a Nautilus (the only Patek he knows).
To the horologically educated, the multireferencial intertext of the watch is overwhelming and yet another proof of the genevoise maison. The curvature of the vertical edges is alchemical on several layers (squared circle, transformative Work of a prime element into its sublimized form and elevation, mutual acclimatation of opposites further seen in metal textures, the list could go on) ; the sizing is strict numerology (45 rpm, another circular reference ; hexagonal number pointing to the elegance in the simplicity of the square compared to the OTHER geometric watch with hexagons ; 45 in the enneagram points to the strength of individuality that will generate envy among those on the outside [non-owners])
