Nebula 40 Steel, Golden: A Star of Elegance and Horological Complexity
The Golden version of the Nebula 40 Steel marks a new era for Arnold & Son. Featuring a redesigned 40 mm steel case, this watch boasts an aesthetic that is both modern and timeless, where each element finds its place in exceptional visual harmony. The slenderness of the case, with its 9.10 mm profile, highlights a skeletonized caliber whose complexity fascinates as much as it dazzles.
In this gold edition, the movement’s components are illuminated by a warm hue that sublimates the finishing of the A&S5201 caliber. Designed specifically for the Nebula, this caliber features a seven-bridge architecture, arranged with perfect symmetry around the center, reminiscent of the stellar arms of a nebula. The bridges, functional and delicately skeletonized, offer a play of transparency that draws the eye to the very heart of the movement.
This vibrant heart, which combines two large barrels in series for a 90-hour power reserve, is reinforced by exceptional finishing. Arnold & Son’s “Rays of Glory” adorn the bridges, adding sparkle and contrast, while satin-finished surfaces and polished chamfers create a remarkable visual dynamic.
The Nebula 40 Steel, Golden, stands out not only for its refined elegance, but also for its inner strength, offering a unique watchmaking experience where aesthetics meets technology in perfect balance.
