La Esmeralda Tourbillon ‘A Secret’ Eternity Edition is housed in a 43 mm pink gold case. It features Three Gold Bridges in a matching hue and is endowed with a honey colour Grand Feu dial. The case, lugs, bezel and buckle are intricately engraved and pay homage to the historic pocket watch of 1889. The dial is enlivened with a combination of sunray and circular guilloché, expertly imparted by hand using a traditional rose engine lathe. At the heart of the watch sits the Signature Tourbillon with Three Gold Bridges, the Manufacture calibre GP09600. Equipped with a discreet white gold micro-rotor, located beneath the barrel, the movement offers the convenience of automatic winding and plays host to golden engravings, referencing the patent filed for the Tourbillon with Three Bridges movement in 1884.
