Three Faces of Elegance
Each dial execution reveals a different facet of this collection – from the smooth depth of enamel, through the radiant sunray brush effect, to the delicate texture of a sandblasted surface. This diversity creates a rich and sophisticated visual language, complemented by a carefully chosen color palette that gives each version its own identity. Together, these finishes allow the watches to express elegance in three distinct ways, while maintaining a unified and thoughtful design.

Powered by the Sellita SW240-1 movement
The mechanical automatic movement is among the most sophisticated achievements of horology – a self-contained world of gears, springs, and jewels that transforms wrist movement into stored energy. At the heart of this model beats the Sellita SW240-1, a Swiss caliber operating at a frequency of 28,800 semi-oscillations per hour with a power reserve of 41 hours. Twenty-six jewels reduce friction at every key point, ensuring reliable precision day after day.

Two disks, one rhythm
What appears on the dial as two simple indications is in fact a precisely layered mechanism. Two independent discs – one showing the days of the week, the other the dates from 1 to 31 – are driven by interconnected gearing that ensures their precise operation. Every midnight, both indications change instantly and in perfect synchronisation with the rhythm of the movement that measures every second of the day.
