Girard-Perregaux Three Bridges and La Esmeralda

From the 1867 tourbillon to the 1889 gold medal

Girard-Perregaux's own history says Constant Girard presented a tourbillon with three parallel bridges at the Neuchâtel Observatory and at the Paris Universal Exhibition in 1867. The bridges are the structure of the movement: an upper bridge for the mainspring barrel, a middle bridge for the wheel train, and a lower bridge for the tourbillon. Their arrow-shaped ends became a visual signature, not only a functional part.

Girard patented the refined architecture in the United States in 1884. At the Paris exhibition of 1889, La Esmeralda, with its three gold bridges, won a gold medal. The name is tied to that elaborately engraved gold pocket watch. The design is the link between the nineteenth-century piece and the watches that carry the name today.

The modern La Esmeralda Tourbillon

The modern La Esmeralda Tourbillon was introduced in 2016 for Girard-Perregaux's 225th anniversary, and it won the tourbillon prize at the 2016 GPHG awards. The pink-gold reference uses caliber GP09400-0004, a self-winding movement with at least 60 hours of reserve, a 3 Hz frequency and a tourbillon 14.3 mm in diameter. The movement measures 36.60 mm by 8.41 mm, and the case is about 44 mm across and 14.55 mm thick.

The key technical feature is the automatic rotor, which sits concentrically beneath the barrel rather than above the movement. That keeps the bridges uncluttered and allows a larger barrel, which is how the reserve grows from the traditional model's 48 hours to at least 60. Other references use other GP09400 variants, and a later Eternity Edition uses a different family, so check the caliber name on the papers.

Owners should also know what to expect from the bridges day to day. The gold bridges are finished to be seen, and a watch left loose in a pocket or against a hard surface can pick up marks on their edges. A soft pouch, a flat storage position and care when changing the strap will keep the movement's finish in the condition the brand intended.

Servicing a tourbillon with gold bridges

A service on a Three Bridges watch is a tourbillon job, and the bridges are both structure and finish. Removing and reassembling them can mark the hand-applied polishing, bevels and straight-grained flanks that the brand describes. Ask the shop how it will protect the bridges during disassembly, and whether it will polish them in-house or send them to a specialist finisher.

Ask how long the watch will be out, and expect a tourbillon service to take longer than a simple movement service. A shop that quotes a short turnaround for a tourbillon with polished bridges should explain what it plans to skip. Confirm that the regulation will be checked in several positions before the watch goes back to you.

The brand's own service is the safest choice for a modern La Esmeralda, particularly for regulation and for any work that touches the bridges. A watchmaker who regularly services tourbillons can handle a watch out of warranty, but ask for the regulation method and the timing results before and after the service. Tourbillon watches are costly to run, so a clear quote with a named scope of work is essential.

Buying a pre-owned Three Bridges watch

Start with the papers, the reference and the caliber. A modern La Esmeralda carries a specific reference and a movement name, and both should match the caseback and the documentation. Ask whether the watch has been opened and by whom, since a tourbillon that has been serviced by an unqualified hand is hard to value.

Check the bridges for scratches, dull polish or uneven bevels, and look at the dial and the case for signs of refinishing. Ask the seller or an independent to confirm the tourbillon runs and that the watch is regulated. A tourbillon that will not run steadily, or that shows signs of a hard knock, needs a full inspection before any purchase.

Ask whether the bridges are original and whether they have been repolished. Repolishing changes the bevels and can soften the edges that the design depends on, so a bridge that looks uniformly bright may have been reworked. A written note from the watchmaker who examined the movement is the best evidence available.

Care and originality for a grand complication

Gold cases and gold bridges need gentle handling. Store the watch flat and away from magnets, and avoid knocks that can shift the tourbillon's cage or the bridges. Keep the box and papers together, since a complete set matters more for a grand complication than for a simpler watch.

Ask for the tourbillon cage and the automatic rotor to be checked during the inspection. The cage should move freely and the rotor should turn smoothly without drag. A cage that catches or a rotor that grinds can point to a bearing problem that becomes costly if it is left alone.

Refinishing a tourbillon case or bridge changes the value and can change the look of the movement. Ask the shop to list every part replaced and to note any polishing. A Three Bridges watch with its original finish, a clear service record and its full set of documents is the one that holds its value.
