A SYMBOL OF PROTECTION
SPIDER AND BASEPLATE IN GEM-SET GOLD
The rhodium-plated gold spider, set with precious stones, forms an integral part of the movement. The opisthosoma, the abdominal part of the spider’s body, stiffens the tourbillon bridges, and its legs support the two barrels.
The whole baseplate is machined from 18K white gold, polished by hand and then black rhodium-plated. Taking the spider web as its motif, the baseplate is then decorated and set with hundreds of black sapphires, an aesthetic tour-de-force.
