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 37 mm Mother-of-pearl Ceramic sits within Laurent Ferrier's Grand Sport Tourbillon line, introduced in 2010. It carries the house codes established since 2010 — ceramic case, mother-of-pearl dial and in-house automatic — and is one of the references collectors use to date the evolution of the collection.
Interesting facts
- The bracelet tapers across its length, which is why the profile looks thinner on the wrist than the specification suggests.
- Early production dials show a slightly different minute track, and collectors pay a premium for them.

Brand history
Laurent Ferrier has spent more than 16 years refining a single idea: a watch should outlive its owner. From the earliest workshop pieces to today's Classic Origin, the house has balanced technical ambition with a recognisable design language, and its collections remain among the most closely followed by collectors worldwide.
Laurent Ferrier established Laurent Ferrier in 2010, working from Switzerland at a time when precision was measured by hand. The founder's obsession with finishing and accuracy still defines every Laurent Ferrier calibre produced today.
