Girard-Perregaux - Chronomètre à quartz

European Watch, Clock and Jewellery Fair 1977 BF 305
This very thin Girard-Perregaux quartz watch has earned the title of “Quartz Chronometer” after successfully passing stringent, official tests - proof of its accuracy but, even more, of its extreme reliability. Classically styled water-resistant case in 18K yellow gold. (GIRARD-PERIREGAUX - Quartz Chronometer)
