A model following the design spirit of the watches of the 1960s and a tribute to Girard-Perregaux’s technical advances in the field of chronometry, crowned by the Neuchâtel Observatory Centenary Prize. A classic timepiece in terms of functions and lines: very thin round case, entirely polished, softly domed with curved lines (lugs, bezel, sapphire crystal and case-back). Strap perfectly integrated to the case for maximum wearing comfort. Polished leaf-shaped domed hands and “baton-type” hour-markers for perfect readability. The first ever “authentic classical watch in a large size” with its 44 mm case diameter. The Calibre GP01800-0004 Reliable and manufactured in-house, the movement is made of 190 components. The see-through case-back reveals the gold oscillating weight decorated with Côtes de Genève.
