Harmonious, radiant and intense, the Nebula’s skeleton movement reveals a structure in grey and blue tones. It combines steel with a PVD treatment on diametrically opposing bridges for a perfectly chic visual effect. In addition to being the most symmetrical of Arnold & Son’s watches, it is ultra-thin, at just 8.73 mm. Available with a steel bracelet or a blue rubber strap, the Nebula 41.5 Steel radiates cool and intense elegance. The first generation of the Nebula established its place in the House’s galaxy. Drawing on the legacy of John Arnold, a new star emerges to join this collection. The Nebula 41.5 Steel introduces different colour treatments, new finishes, and new, even more powerful and attractive details.
