Voisin Aérosport
Ice Blue

Hours, minutes and seconds are organised through depth rather than graphics alone. The running seconds occupy their own sector at four o’clock, while the hours and minutes form the principal display and are themselves constructed from two separate dial elements.

Information is therefore organised architecturally. The dial appears pure and restrained at first glance, while its construction reveals itself progressively when observed more closely. Its expression of Art Deco comes through structure rather than ornament.

Its apparent simplicity conceals a highly complex construction based on a succession of steps, surfaces and contrasting finishes.

The stepped bezel is divided into two distinct levels. Its upper surface is circular-grained, while the lower step is subtly inclined and mirror-polished. The contrast between the two changes with the light, emphasising the geometry of the case without resorting to additional ornament. This construction continues through the caseband, where different levels are articulated by an inserted circular-grained ring. The lugs follow the same principle, with a two-step architecture and circular satin finishing across their upper surfaces. Rather than treating the bezel, caseband and lugs as separate elements, each contributes to a continuous architectural composition.

At ten o’clock sits another distinctive element: the crown.

Its position deliberately disrupts the conventional symmetry of the watch, while its sculptural construction complements the geometry of the case. A central recess divides its volume, creating a crown that is functional but also architectural in character.

The sapphire crystals are treated with multiple layers of anti-reflective coating on both surfaces. Reflections are reduced to such an extent that the crystal almost disappears, leaving the dial and its different physical levels visually unobstructed.

The complexity of the case is therefore expressed not through decoration, but through construction, finishing and the interaction of surfaces with light.

The calibre supports two distinct dial assemblies: one dedicated to the sectorial running seconds at four o’clock and a second, main assembly carrying the hours and minutes. The latter is itself constructed in two parts, allowing the indications to occupy different physical levels.

Movement and dial are therefore conceived as a single architecture. The tridimensional appearance of the Voisin Aérosport is not simply a decorative construction placed over a conventional calibre; it is made possible by the mechanical configuration beneath it.

The choice of manual winding is equally deliberate. Winding the watch establishes a direct relationship between the wearer and the mechanism, reflecting a period in which interaction with mechanical objects was an ordinary part of daily life. The ALB04 is also COSC-certified, underscoring that precision is not treated as a technical footnote, but as a fundamental design requirement.
The movement showcases a refined combination of traditional Swiss watchmaking finishes, highlighting the beauty of its mechanical architecture and the attention devoted to every detail.

The bridges are adorned with elegant, radiating Côtes de Genève, creating a distinctive play of light across their surfaces. The winding wheels feature fine double colimaçon, providing a subtle contrast to the linear decoration of the bridges.

Traditional perlage decorates the mainplate, including the surfaces concealed beneath the dial. This meticulous finishing, applied even to components not normally visible, reflects a commitment to craftsmanship that extends beyond purely aesthetic considerations.

The movement is further enhanced by polished screw heads, gold-toned engravings, and the vibrant accents of ruby jewels. The exposed balance assembly introduces additional visual depth, while the interplay of brushed, grained, and polished surfaces creates a harmonious and sophisticated composition.

Together, these traditional finishing techniques celebrate the heritage of Swiss fine watchmaking, combining mechanical precision, meticulous craftsmanship, and understated elegance.

Not as a tribute or commemorative object. Not as a watch decorated with references to an automobile. But simply as the kind of watch that might have belonged in his world: precise, mechanically considered and intellectually aligned with his work.

The distinction is fundamental to the project. Rather than reproducing elements of the C28 Aérosport, the watch seeks to share its underlying culture.

Voisin’s work was shaped by aviation and engineering, and by an interpretation of Art Deco in which geometry, proportion and structure played essential roles.

The Voisin Aérosport approaches this language without visual quotation or stylistic mimicry. It is not a contemporary watch dressed as an object from the 1930s, but an imaginary period piece: a watch that never existed, conceived for a man who did.
