HERMÈS Arceau Petite Lune Large Model automatic blue dial blue leather strap 38 mm

Arceau Petite Lune: the poetry of time by Hermès

Designed in 1978 by Henri d’Origny, the Arceau line quickly became an icon of Hermès watchmaking. Its round case with asymmetrical lugs, inspired by an equestrian stirrup, embodies the Maison’s saddle-making heritage while giving it an instantly recognizable style. In this Petite Lune version, presented in a 38 mm large model, Hermès offers a vision of time that extends beyond hours and minutes, venturing instead into the dreamlike realm of the stars. A timepiece that blends celestial poetry, horological expertise, and jeweler’s art.

A precious case, set with diamonds

Crafted in polished steel, the 38 mm case is adorned with a descending setting of 70 diamonds (0.805 ct). This sophisticated technique lowers the setting slightly along the side of the bezel, producing a softer, more diffused brilliance. The diamonds catch the light with every movement of the wrist, transforming the watch into a true jewel of fine watchmaking. Protecting this sparkling case, a domed anti-reflective sapphire crystal enhances the depth and radiance of the dial.

A celestial dial, like a miniature painting

The lacquered blue gradient mother-of-pearl dial unfolds like a nocturnal sky, shimmering with changing reflections. Its surface is dotted with seven diamonds (0.019 ct), arranged like a discreet constellation that invites daydreaming. At 10:30, the moon phase appears off-centered, stylized as a crescent adorned with silver stars, reinforcing the poetic and artistic dimension of this piece. As each dial is hand-crafted, the gradient and iridescent nuances are unique, making every watch a singular miniature sky.

A Manufacture Hermès movement

Beneath the aesthetic beauty lies technical mastery. The Arceau Petite Lune is powered by the Hermès H1837 caliber, an automatic mechanical movement developed at Manufacture Vaucher Fleurier, Hermès’ partner. Beating at 28,800 vibrations per hour and offering a 42-hour power reserve, it ensures precise timekeeping. The addition of the Petite Lune module enriches the movement with this poetic complication, seamlessly integrated. Through the transparent sapphire caseback, traditional finishes can be admired, reflecting the artisanal care devoted to every component.

Everyday elegance and comfort

This horological creation comes fitted with a short sapphire-blue alligator leather strap, interchangeable and secured by a polished steel pin buckle. A true symbol of refinement, this leather, selected and crafted by Hermès’ master leatherworkers, is celebrated for its suppleness and its unique patina that develops over time. Water-resistant to 3 bar, the watch is suitable for daily wear, though Hermès recommends avoiding contact with water when paired with a leather strap. As always with Hermès, each strap is unique, with subtle variations in scale pattern and hue.

The Hermès spirit: reinventing time

More than a watch, the Arceau Petite Lune is an invitation to view time differently. True to the Hermès philosophy, it does not merely measure hours, but transforms them into a sensory experience, blending poetry and elegance. With its celestial dial, radiant gem-setting, and Manufacture movement, it perfectly illustrates the art of Hermès: turning utility into desire, and timekeeping into a jewel, a work of art, and a refined instrument all at once.
