Noble colours
This anniversary edition can be worn with a choice of three bracelets: three-link steel, garnet calfskin and technical fabric in the same colour. The skeletonised main plate and gold-finished barrels complement the Eastern Arabic numerals on the garnet-hued flange. The palladium-plated bridges echo the steel of the case, creating an equilibrium between materials and colours.
Seven bridges
Designed with purity of line in mind, the Nebula 40 Steel features a rounded flank and deep lugs that highlight the essential: its signature movement. Inspired by nebulae and their spiral arms, the architecture of the A&S5201 calibre is based on seven functional and harmoniously arranged skeletonised bridges. Facing the centre, they present a radiating and transparent symmetry that forms the collection’s essence.
Power and endurance
Equipped with two large series-coupled barrels, the Nebula 40 Steel offers a remarkable 90-hour power reserve, rare in skeletonised pieces but typical of Arnold & Son calibres. Their energy drives the entire gear train, which follows the star-shaped arrangement of the bridges. The balance at the end beats at a frequency of 3 Hz, demonstrating this exceptional movement’s vitality.
