Guilloché Enamel Grand Sonnerie

The Voice of Time

The Guilloché Enamel Grand Sonnerie is among the rarest and most demanding of all horological achievements — a watch that strikes the hours and quarters automatically, like a miniature cathedral clock on your wrist. Its hand-engraved guilloché dial, fired in grand feu enamel at 800°C, is a canvas of burgundy and gold that took a single artisan three months to complete.

Exceptional Complications

Craftsmanship

The 43mm 18k yellow gold case houses a movement of 752 components — one of the highest complication counts ever achieved in a wristwatch. The guilloché pattern on the dial is hand-engraved using a 19th-century rose engine, a craft mastered by fewer than a dozen artisans worldwide. Each piece requires 18 months to complete from start to finish.

Some watches tell time. This one announces it.
