Historical significance

Laurent Ferrier Grand Sport Tourbillon 39 mm Mother-of-pearl Carbon sits within Laurent Ferrier's Grand Sport Tourbillon line, introduced in 2010. It carries the house codes established since 2010 — carbon tpt case, mother-of-pearl dial and micro-rotor automatic — and is one of the references collectors use to date the evolution of the collection.

Interesting facts

• The case is finished by hand, alternating polished and satin-brushed surfaces in a single pass so the edges stay razor sharp.
• The movement's bridges are decorated even where they will never be seen once the watch is cased.
