Girard Perregaux have reintroduced the 1966 Chronograph Doctor’s Watch. The watch has a retro look with modern features, including an orange circle on the watch face and a pulsometer scale for measuring heart beats. This watch, which has a black leather strap, is available with a rose or white gold case and is powered by a GP030C0 mechanical movement with automatic winding. Just ten pieces of each style will be available.
