Arnold & Son Nebula 40 Steel, Blue Edition Design Philosophy: Radiating Harmony

JUNE 10 2025    |    Novelties

The watch features a star-shaped arrangement of seven bridges, radiating from the center like a nebula, giving it both structural integrity and visual depth.

The movement is laid out with four lines of symmetry, aligning the barrels, balance, and small seconds for a harmonious aesthetic.

Technical Excellence: A&S5201 Calibre

Dual barrels provide an impressive 90-hour power reserve.

Components are arranged in a kinematic chain around the edge, enhancing both function and form.

The crown mechanism is inverted and placed on the case-back side for symmetry with the first wheel at 9 o’clock.

Aesthetic Details

The lower levels of the movement are treated with a rich blue PVD, contrasted by palladium-finished bridges and components.

Includes horizontal satin brushing on the dial side and Arnold & Son’s signature ‘Rayons de la Gloire’ motif on the reverse.

The 40 mm diameter and 9.10 mm thickness ensure elegance on the wrist.

Strap & Bracelet Options

Available with a blue alligator leather or rubber strap.

Also offered with a three-link steel bracelet that highlights the watch’s symmetry and skeletonized beauty.

Timeless Precision: Honoring Horological Legacy and Legendary Friendship

Arnold & Son unveils the final chapter of its Constant Force 11 collection with the Constant Force Tourbillon 11 Platinum Edition, a limited series of just 11 pieces. This exceptional timepiece celebrates 260 years of horological heritage, paying homage to the legendary friendship between John Arnold and Abraham-Louis Breguet.

Crafted in platinum (Pt950), the 41.5 mm case houses a dial of hand-guilloché tremblé engraving in 18K yellow gold, inspired by the fern-covered moors of Tintagel, Cornwall—Arnold’s birthplace and the mythical land of King Arthur. The white opal subdial and visible constant force mechanism add depth and elegance.

Powered by the A&S5219 manual winding calibre, the watch features a constant force mechanism, one-minute tourbillon, and true-beat seconds. The engraved plate reads: "To the revered memory of John Arnold and Abraham-Louis Breguet. Friends in their time, legendary watchmakers always."

gérald genta Introduces Gentissima Oursin 41 with Meteorite Dials

gérald genta continues its legacy of audacious elegance with the launch of two new references in the Gentissima Oursin collection: Blue Meteorite and Green Meteorite. These timepieces mark a bold evolution of the iconic design first imagined by Mr. Gérald Genta in 1994, inspired by the delicate yet resilient form of the sea urchin.

A Design Born from Nature and the Cosmos
The Gentissima Oursin 41 features a 41mm sandblasted Grade 5 titanium case, meticulously set with 234 white gold beads, echoing the organic geometry of the sea urchin. At its heart lies a dial carved from a fragment of meteorite—a material born from the stars—making each watch a unique, one-of-one creation. The natural crystalline structure of meteorite ensures that no two dials are alike, offering collectors a truly rare expression of artistry.

Sporty-Chic Meets Haute Horlogerie
Combining rubber straps and titanium architecture with luxurious gold accents, the Gentissima Oursin 41 is designed for everyday wearability without compromising sophistication. A curved sapphire crystal, faceted with a subtle octagonal profile, protects the dial and enhances its dynamic character. Gold hands filled with Super-LumiNova featuring a pink hue—a tribute to Mr. Genta’s favorite color—ensure legibility and elegance.

Mechanical Excellence
Inside beats the Zenith Elite GG-005 automatic movement, boasting a 50-hour power reserve, 4 Hz frequency, and an 18K yellow gold oscillating mass, visible through a sapphire caseback. With 50m water resistance and a comfortable rubber strap, this timepiece is as practical as it is artistic.
