Arnold & Son Nebula 2016 is a perfect example of watchmaking architecture, a new manual winding movement developed and designed to be as opened as possible. The design and structure of the movement let you look into the heart of this in-house caliber. The designer, my good friend Sébastien Chaulmontet, created an almost perfect mirror-like symmetry, blending mechanical engineering and art. This Nebula is in stainless steel, 41.5mm, 90 hours power reserve, priced at CHF13,500
