One only need consider the complexity of the case, or

the technical challenge the bracelet represents, to understand that Audemars

Piguet has done something very special by machining this Royal Oak Perpetual

Calendar in ceramic. It marks a first in this iconic collection by the brand,

made possible only after 600 hours of research and development. The ceramic

bracelet alone takes 30 hours to produce, which is five times longer than for a steel bracelet. This new direction in no way takes away from the spirit

of the Royal Oak. All the hallmarks imagined by its designer, Gérald Genta, are

in evidence, in particular the Grande Tapisserie dial that is the backdrop for

the Perpetual Calendar indications. Behind the scenes beats a manual-wind

movement, Calibre 5134.
