When Girard Perregaux re-purchased one of their own vintage pocket watches with a three bridge tourbillon in 1981, it occurred to them to bring this concept back to life in a modern wristwatch. Together Willy Schweizer and Denis Schnegg, known as "Mister Tourbillon" of Girard Perregaux, completed the project successfully late in 1982; a small series of 20 examples was produced, which were all submitted to chronometer trials.
The movements with three bridge tourbillons produced since then are all very different in style. This movement is signed Denis Schnegg and features a particularly elaborate, hand engraved ornamentation by P. Wiget which covers the whole movement and the 12 mm small micro-rotor.
