Girard-Perregaux

European Watch Clock and Jewellery Fair 1980 BF 353
Watches increasingly come in pairs this year, including in up-market collections. These two Girard-Perregaux designs in 18K yellow gold are set with lapis lazuli segments. They feature the new extra-thin (2.50 mm) GP 360 and GP 380 movements, with instant timezone correction (GP 360 and 380), centre seconds and calendar (GP 380). (GIRARDPERREGAUX)
