minute repeaters, perpetual calendars, equation of time, and the split-seconds chronograph foudroyante, all come gloriously to life under the experienced hands of Girard-Perregaux's master watchmakers. Many of these staggering mechanical complications are joined together in certain timepieces, an accomplishment exemplified by the the Opera watch series, or the famous Enzo Ferrari Perpetual Calendar Tourbillon watch. The celebrated golden bridge tourbillon movements, which have brought the House of Girard-Perregaux so much fame, are also found within the Haute Horlogerie collection, and are presented in several variants, in both the Vintage 1945 format, as well as the classical round case. Technically brilliant, and flawlessly crafted, the Haute Horlogerie watch collection from Girard-Perregaux upholds the traditions of excellence inaugurated by Constant Girard.
