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.
