There is a singular, fleeting moment at the edge of the day when the world is suspended in a wash of sapphire light. The Excalibur Monotourbillon Blue Hour captures this ephemeral magic, translating the poetic stillness of twilight into a feat of uncompromising technical expertise.

This 42 mm creation is a profound study in the art of the atmosphere, transforming the ethereal beauty of the sky into a horological statement that feels both grounded in precision and lifted by imagination.

The architecture of the piece finds its most luminous expression in the bezel, where a meticulously curated gradation of fifty blue sapphires and ten white diamonds creates a shimmering ombre effect. This artful arrangement evokes the subtle and enchanting transition of light during the storied blue hour, mirroring the depth of a sky that refuses to be silent. Beneath this radiant frame, the skeletonized movement reveals the Maison's mastery of the monotourbillon, offering a rhythmic pulse that grounds the celestial inspiration.

It is a rare work of art that captures a nature-born moment and grants it the permanence of haute horlogerie.
