Named after the birthplace of stars, Nebula has an openwork movement supported by seven chamfered, triangular bridges based at the border of the bezel, and a horologic heart.
The watch’s 90-hour power reserve and its near-mirror symmetry with the small second display are evidence of Arnold & Son’s incredible attention to detail. Nebula is proportioned both horizontally and vertically. A reverse view of the configuration reveals that this visual balance extends to the back of the movement as well. The rear sapphire crystal also provides glimpses of three additional bridges, the skeletonized main plate and the 18-karat-gold chatons.
The proportions and ratios of diameter versus height and the size and placement of every gear and wheel were taken into consideration when creating Nebula. The timepiece is available in stainless steel or in an 18-karat red-gold case.
