Girard Perregaux 99000
Girard-perregaux, the first generation of the Three Gold Bridges, model: 99000, manual winding, 39mm diameter, 18K rose gold, original. The Three Gold Bridges of Girard-Perregaux was invented by watchmaking master CONSTANT GIRARD, who confirmed the feasibility of using gold in movements and successfully developed the Three Gold Bridges tourbillon movement, shocking the watch industry. Unlike pocket watches with a single plate, CONSTANT GIRARD designed the centers of the balance wheel, mainspring wheel and drive wheel in a straight line, and then fixed them with three parallel strip-shaped plates. The arrow design of these three parallel plates is what we call the "three golden Bridges".
