The smooth rounded 18-carat white-gold case of the Galet model (“galet” means “pebble” in French) plays host to two features unique to Laurent Ferrier. The first is the “secret” mechanism, which can be activated on demand by the pushbutton in the crown and can be programmed to open over a specific 60-minute period chosen by the owner. This opens up a 240-degree aperture on the dial to reveal a custom-made decoration on the dial produced to the customer’s requirements by renowned enamel artist Anita Porchet. The second feature is found in the movement, which uses two inversed hairsprings in the manually-wound tourbillon mechanism to cancel out the effects of the Earth’s gravity.
