Designer

Emmanuel Gueit

Emmanuel Gueit came from a family of Geneva jewellers and was barely into his twenties when he drew the oversized Royal Oak Offshore in 1993 — a watch the house's traditionalists resisted and collectors turned into an icon.

Historical significance

Laurent Ferrier Grand Sport Tourbillon 41 mm Ice 18k sits within Laurent Ferrier's Grand Sport Tourbillon line, introduced in 2010. It carries the house codes established since 2010 — 18k yellow gold case, ice blue dial and in-house automatic — and is one of the references collectors use to date the evolution of the collection.

Interesting facts

• The movement's bridges are decorated even where they will never be seen once the watch is cased.
• The bracelet tapers across its length, which is why the profile looks thinner on the wrist than the specification suggests.
• The case is finished by hand, alternating polished and satin-brushed surfaces in a single pass so the edges stay razor sharp.
