Built like a radiant star, the Nebula is bursting with light. Now, the symmetrical elegance of the Nebula collection is entering a new orbit with the introduction of a new color combination, alternating between grey NAC and rose gold. The contrast further highlights the striking structure of the watch’s skeletonized caliber.

Since its creation, Nebula has been a star. Its stellar mechanism, the A&S5201 caliber, is the gravitational force of this collection, giving it its appearance, identity, and strength. Redesigned with a movement whose finishes are more advanced than ever, the Nebula collection continues its expansion.

Arranged in a star around the edge of the caliber, the openworked, chamfered, and satin-finished bridges create the impression of a watchmaking explosion and a sense of rhythm and control. Positioned at regular intervals, these bridges are identical in shape but different in size and reflect the aesthetic heritage of John Arnold’s chronometers.
