Nebula 40 Steel

A harmoniously arranged skeletonised calibre with an evolved and subtle watchmaking style.

Limited to 88 pieces.

A star with seven bridges

Arnold & Son has reworked its Nebula collection, giving it a more striking case with a universal diameter of 40 mm while retaining its remarkably finished movement and unique abundance of watchmaking tradition.
The aesthetics of the Nebula collection are unlike any other skeleton: its structure conveys watchmaking spirit, its style expresses unique elegance, and the overall effect is one of outstanding finesse.

Seven bridges

The new generation of Arnold & Son cases focuses on the purity of lines and curves. Softened flanks and plunging lugs strip back the aesthetics of Nebula 40 Steel to the essential: its signature movement, the central star around which the aesthetics of the collection revolve.

The calibre was born with Nebula, for which it was specifically developed. Its architecture, inspired by the nebulae from which the arms of stars radiate, is what gave the collection its name. Here, these arms are represented by seven bridges, all functional, skeletonised and harmoniously arranged. Facing the inside of the watch, they converge towards its centre, creating an incomparable impression of order, symmetry and transparency.

Relief

The case of the Nebula collection has been redesigned, modernised and refined. With streamlined lugs, a softly rounded bezel, a more vertical case middle and a diameter of 40 mm in harmony with its thickness of just 9.10 mm, this steel case opens a new chapter for the collection. Featuring the A&S5201 skeletonised calibre offering an ultra-graphic layout, Nebula retains its identity as a watch whose movement fascinates, captivates and draws the eye into its depths.
