Arnold & Son Expands Its Watch Galaxy With a New Blue Nebula

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 8.73mm. Available with a steel bracelet or a blue rubber strap, the Nebula Blue radiates cool and intense elegance.

The first generation of the Nebula established its place in the watch brand’s galaxy. Drawing on the legacy of John Arnold, a new star emerges to join this collection. The Nebula Blue introduces different color treatments, new finishes, and new, even more powerful and attractive details.

Inside and Out

The name Nebula was chosen as a reference to the giant cloud of dust and gas in space. Some nebulas emerge from the gas and dust expelled when a dying star, like a supernova, explodes. Other nebulas are regions where new stars start to form. The seven bridges on the dial side of this timepiece radiate from the center outwards, giving this sculptural movement the impression of a cosmic explosion.

The A&S5201 caliber was specially created for this piece and brings all its character. It is set apart by its skeletonization and almost perfect symmetry. The traditional shape of its bridges harks back to John Arnold’s chronometers and their openworked structure accentuates the feeling of lightness in a very mechanistic design.

Two-Tone

The bridges of the A&S5201 caliber are palladium-treated, giving a sheen that echoes the steel case. The main plate, barrel covers, and dial flange have been colored with a blue PVD treatment. The Nebula Blue is fitted with either a three-link steel bracelet or a ballistic-type rubber strap with a woven-look surface. The two-tone aesthetic adorns the interior and exterior, the substance of the watch and the details.

Fully Equipped

The A&S5201 caliber was conceived as a skeleton mechanism instead of being modified by removing material. The result is a completely clear and legible display on both sides.

One by one, the components reveal their subtle finishes, adopting strict, fluid forms. The sum of these details and the overall approach make this caliber a special case in the exclusive circle of skeleton movements. For instance, it presents a total power reserve of 90 hours, only requiring it to be hand-wound every three-and-a-half days. At 4mm thick, the caliber contributes to the piece’s overall slimness. The Nebula Blue measures 8.73mm thick, making it a natural member of the ultra-thin category.

High Altitude

The A&S5201 caliber has also undergone several developments in addition to the new blue coloring. The balance wheel is now rhodium-plated to match the gear train and perfectly coordinate with the small seconds placed opposite. The main plate, particularly its reverse side, features “Rayons de la Gloire” finishes, a surface treatment like sunray-brushing in a wave shape. Arnold & Son rises magnificently to the challenge of sending its Nebula Blue into a new orbit.
