Shriya Zamındar, reporting for Vogue India, pays a visit to Rado's watch manufacturing facilities in Switzerland:

The brand uses raw materials like tiny globules of clay, which then go to through different stages of heating, cooling and compression to form a watch’s skeleton.

The recipes of the secret sauce for each series of ceramic watches dictate how capsules of different colours are mixed in an actual cauldron to form completely new shades. Not following the ingredient list or respecting the exact cooking time can have potentially disastrous results.
