Girard-Perregaux 9050 Ultra-Slim Dress Watch Vintage

Key Points from the Discussion

• The Classique Elegance line, which includes the Ref. 9050, debuted around 1994 under Gino Macaluso's leadership, marking a shift from earlier ETA/Peseux-powered models to in-house GP3xxx calibres. These early Classique Elegance models, typically 34mm in diameter, were the first to feature GP's newly introduced manufacture movements.
• The Ref. 9050 was the inaugural Girard-Perregaux reference to house the new Calibre 3000 (no date), while the Calibre 3100 (with date) first appeared in the Laureato Ref. 8010 in 1995, effectively defining the modern Laureato line.
• Girard-Perregaux supplied the Calibre 3100, not the Calibre 3000, to Vacheron Constantin for their first-generation Overseas model, released in 1996.
• The author's archive extract confirms the Ref. 9050 was the first model equipped with the new in-house GP Calibre 3000, suggesting its potential role as a prototype or demonstrator for other high horology houses like Vacheron Constantin.
• The curious placement of the seconds sub-dial on the Ref. 9050 shows a design lineage inspired by Vacheron Constantin and Breguet, reflecting a broader historical design trend in high watchmaking.
• Among the Classique Elegance models, the skeletonized versions are exceptionally rare, with manually skeletonized and hand-engraved gold-plated movements, estimated to be fewer than 25 units produced.
