Today we’re taking a close up look at the Girard-Perregaux Tourbillon with three gold Bridges. Now celebrating its 125th year, this mechanism (which was patented in 1884) is undoubtedly the manufacture’s most storied creation.
For this newest edition, the mainplate is now sanded to enhance the three gold Bridges and the openworked barrel drum opens onto the micro-rotor. The 41mm case is available in either pink or white gold, showcasing the three iconic arrow-shaped parallel Bridges, which are entirely hand-made, “rounded-off” (a beveling technique which gives the bridges a domed shape) and mirror-polished.
The GP09600 self-winding movement operates in the background. The 80-component tourbillon system is just 10 millimeter in diameter. The cage, like the escapement and pallets bridge are chamfered and hand-polished, as are the gold adjustment screws. At 12 o’clock, the barrel drum is skeleton-crafted to reveal the oscillation of the platinum micro-rotor.
The Girard-Perregaux Tourbillon with Three Gold Bridges is completed by a black alligator leather strap with pink or white gold folding buckle.
