Before its new life as this remarkable wristwatch, the Esmeralda Tourbillon was a pocket chronometer, referred to as the Tourbillon under Three Gold Bridges. The very one that claimed a Gold Medal at the 1889 Universal Exposition in Paris.

A milestone in the history of Girard-Perregaux, the Tourbillon under Three Gold Bridges is interpreted here with complete respect for the historic watch. The arrow-head bridges supporting the barrel, geartrain and large (14.30-mm diameter) tourbillon have been decorated by hand with mirror polishing, bevelled edges and straight-grained flanks. Each detail confirms the noble origins of this prestigious timepiece. The movement's rotor is mounted co-axially with the mainspring barrel to provide a more than comfortable 60-hour power reserve.

Designed like a “secret” watch, for the first time the new interpretation of La Esmeralda features a cover protecting the back of the model. This element further adds to the precious nature of this creation and promotes a special sense of privileged intimacy with the wearer. The entirely hand-engraved pink gold case picks up the brilliantly executed motifs adorning the 1889 model.

Three horses thus gallop across the outside of the cover, while the interior is engraved with the inscriptions “Tourbillon” and “La Chaux-de-Fonds”, leaving enough space for personalisation by the future owner.
