Girard-Perregaux, Vintage 1945 Power Reserve, Men's Watch, 18K White Gold Polished Case, Leather Strap, Mechanical Automatic Self-winding Movement Born in 1945 and reintroduced into the GIRARD-PERREGAUX collection in 1995, the Vintage 1945 line is as alluring as ever with its strong lines, subtle retro appeal and curved ergonomic case. The GIRARD-PERREGAUX Manufactory has perfected an extremely original column-wheel chronograph movement. The column-wheel is the most effective system for measuring short periods of time with extreme precision. What makes this mechanism truly unique is its position under the dial rather than under the rotor, where it is usually placed in automatic movements.
