Three Gold Bridges span the dial, similar to those fitted to La Esmeralda of 1889. However, on this latest model, Girard-Perregaux has once again made the invisible visible by bringing the horses engraved on the back case of the original pocket watch up to centre stage of this new timepiece. Indeed, two hand-engraved galloping horses form the right and left ends of the barrel bridge and tourbillon bridge. Each bridge is painstakingly finished and features concave bevelling, mirror-polishing, flanks with horizontal ‘traits-tirés’ and rounded off arms. It requires 40 hours to finish each bridge, while the additional engraving found on the barrel bridge and tourbillon takes an extra 50 hours to complete.
