Description

Two Brands, One Celestial Art.

The Santura x Bauche HoroArt collaborative release re-envisions Bauche HoroArt's original Carina Nebula spirit into a new cosmic expression.

At its heart lies a tri-layer material stacked dial construction combining the Amethyst stone with a Purple fume mother-of-pearl dial and Black aventurine glass, orbiting within the brushed elegance of the Santura Novus case.

Each layer of the dial is placed at a subtly different height, depth, and elevation, creating a gentle 3D effect that brings the cosmos to life beneath the crystal. This dimensionality gives the watch its sculptural presence, as if time itself is orbiting through space.

Adding a touch of whimsical exploration, a small rocket motif replaces the 9 and 10 hour markers, subtly skewed to complement the watch’s visual tension and poetic imbalance. This asymmetry evokes the quiet disarray of celestial drift, a design language shaped by the unpredictable beauty of the nebula.

Handcrafted in Indonesia by AQH Concept, the strap features a combination of deep navy-blue Epsom leather and warm brown calf leather
