THIS DESIGN EXPLORES HOW STRUCTURAL ELEMENTS BECOME PART OF THE VISUAL IDENTITY.

THE EXPERIMENT
Rather than hiding the watch's structure, this design explores how structural elements become the visual identity. The six exposed screws on the bezel echo the color of the black soleil dial, creating a continuous link between the dial and the outer case. Combined with the circular brushed bezel and the Ultra Thin profile, these finishes create a composition in which every component contributes precision, sobriety, and visual harmony.

THE MATERIALS
The steel case offers strength and durability while maintaining the slim proportions of the Ultra Thin 1980 collection. The circular brushing on the bezel provides a light texture, while the soleil dial reflects light with delicate variations. The matching screws reinforce the link between the dial and the case, creating a cohesive look that highlights the watch's structure rather than hiding it. The sapphire crystal with blue anti-reflective coating preserves clarity by reducing glare as the light changes

THE COLLECTION
ULTRA THIN
The Ultra Thin collection is defined by its proportions. The case is reduced in thickness by a few millimeters, creating a slim profile that sits close to the wrist. The steel case and integrated bracelet form a compact and continuous silhouette, in which every element reduces bulk. The light and precise structure makes the watch flat, stable, and discreet all day long.
