The “Arche Noire”

In the Islamic tradition, mathematics inspired the shape of the case: a straight slab, the four sides of which represent power, permanence, achievement and justice. It gives off an impression of strength and majesty, softened by curved and bevelled edges as well as by the rounded angles that recall arabesques. The base of the case is in solid gold, an unchanging metal symbolising a promise or an eternal commitment.

The Frères Rochat “Arche Noire” Singing Bird celebrates Islamic art and architecture

At the four cardinal points, six Persian arches join their points to replace the traditional columns. Made of gold and delicately set with black spinel baguettes, they impart a subtle gleam to the whole work and make up four mysterious niches within which shines a sunburst of round spinels. The goldsmith’s work is of exquisite refinement, enhanced by the four finely engraved and gemset domes hiding the screws that hold the piece together.


Métiers d’Art

For more than 200 years, the Frères Rochat Singing Birds have ranked among the most complex, the most precious and the most refined works of horological art. To achieve this level of perfection, Frères Rochat has always worked with the most talented craftsmen, who are alone capable of such exploits. The unique “Arche Noire” Singing Bird is a perfect example.


The cover, in 18-carat gold, is set with nearly housand white round diamonds. The nest, fashioned in a thin plate of 18-carat gold, is cleverly openworked and patiently engraved in a “Fleurisanne” motif. The two-tone bird, which is perfectly smooth to the touch, combines the refinement of white gold with the low weight of titanium. Its eyes are set with round diamonds of great clarity. It sings three tunes — two birdsongs and an extract from Mozart’s 40th symphony — demonstrating its mastery of the 12 semitones of its vocal range.
