Nebula 41.5 Steel is a wristwatch by Arnold & Son.

The name Nebula (English: “fog”) is a reference to the huge gas and dust clouds in space. Some of these nebulae are formed from the matter created in a Supernova, the explosion of a dying star. From other nebulae form new stars. The seven bridges on the dial side of this timepiece run radially from the center to the edge and are reminiscent of a stellar explosion.

The A&S5201 caliber was created especially for this model and gives the watch its appearance. It is characterized by the fine skeletonization and symmetry. The traditional shape of its bridges is inspired by the chronometers of John Arnold.

The bridges of the A&S5201 caliber are coated with palladium, the luster of which harmoniously complements the appearance of the stainless steel case. The plate, the mainspring barrel cover and the dial's chapter ring stand out in color thanks to a blue PVD coating.

The caliber A&S5201 was designed as a skeletonized movement and was not modified to save material. Each component, with its subtle finishes, is clearly recognizable.

In addition to the new look in blue, the caliber A&S5201 underwent several developments. The balance wheel is now rhodium-plated to match the gear train and complement the small seconds hand on the front. The decoration on the plate, especially on the back, is decorated in the motif “Glory Rays Gloria”, a finish that resembles a sunburst and has a wavy shape.

The watch was presented in spring 2022. It is optionally available with a three-link stainless steel bracelet or a strap made of ballistic rubber with a woven look.
