This reference introduces a dual-material composition, combining stainless steel with rose gold accents across the bezel and bracelet links. The result is a visually layered case that shifts between sport and elegance depending on lighting and wear context. The dial maintains the Cubitus signature embossed horizontal pattern, complemented by polished hour markers and hands that enhance readability while preserving a clean aesthetic. Inside, a self-winding caliber ensures consistent timekeeping, engineered with precision components and finished to haute horology standards.

The two-tone configuration gives this model a more expressive personality compared to the steel variant. It appeals to collectors who appreciate contrast and craftsmanship in equal measure. The watch transitions effortlessly between formal and casual environments, offering both visual richness and mechanical reliability in one cohesive piece.
