A striking expression of independent haute horlogerie, this PIERRE KUNZ Spirit of Challenge retrograde wristwatch exemplifies the maison’s fascination with mechanical ingenuity and graphic balance. Crafted in 18K white gold, the 41mm coin-edge case is framed by a finely set diamond bezel, lending brilliance and refinement to an otherwise architectural silhouette.

The black and silver dial is defined by Pierre Kunz’s signature retrograde displays, an elegant choreography of arcing scales and sweeping hands that animate the passage of time with constant motion. Roman numerals anchor the composition, while the layered apertures and contrasting finishes create depth, rhythm, and visual tension. The result is a dial that feels both technical and poetic, designed to be read intuitively yet admired as a work of mechanical art.

Turned over, the sapphire case back reveals the automatic movement, its rotor engraved Spirit of Challenge, a quiet declaration of the brand’s philosophy and the watch’s conceptual foundation. Paired with a black alligator strap and finished with a diamond-set buckle, the watch balances innovation with classical elegance.

A distinctive and collectible creation from Pierre Kunz, produced in limited numbers and accompanied by its certificate.
