1960s Piaget 18ct Pink Gold Square Manual 25mm 901

Here we have a 1960s Piaget Square in 18ct Pink Gold, a definitive example of the brand’s mastery over ultra-thin horology and mid-century glamour. Its 25mm 18ct pink gold square case features a stunning polished finish with a profile of just 4mm, making it one of the slimmest timepieces of its era. With a lug-to-lug length of 34mm and a seamless, integrated feel to the lugs, the watch sits with an elegant, low-profile presence on the wrist. On the right side is a petite crown that barely interrupts the sleek, linear geometry of the case. A flat crystal protects a minimalist dial finished in a warm, patinated soft sunburst champagne/yellow featuring printed ultra-thin indices that echo the watch’s slender proportions. The simple baton hands glide across the dial, driven by a movement that redefined what was possible in mechanical watchmaking. On the reverse, the 18ct gold case back is secured by screws, protecting the legendary calibre within. Inside, the manually wound Piaget Calibre 9P is a true horological icon. Introduced in 1957, this movement measures only 2mm thick, yet it beats at 19,800 vibrations per hour and was engineered for both reliability and high-level finishing. It comes paired with a 16mm leather strap that accentuates the warmth of the pink gold.

This watch is sold “Watch Only” and therefore comes with no original Piaget box or papers. It comes paired with a 16mm leather strap that accentuates the warmth of the pink gold. The watch is from Circa. 1960s is in fair vintage condition for its age, with signs of wear and patina across the watch, as you can see from the photographs. The watch comes with our 12-Months NON-Waterproof Warranty.

This Piaget is a very clear expression of what the brand did better than almost anyone in its era: take extreme technical achievement and wrap it in complete visual restraint. At just 4mm thick, it has that almost surreal quality on the wrist where it feels less like a traditional watch and more like a thin, polished object that happens to tell the time. The square case reinforces that feeling of geometry and precision, with no excess lines or unnecessary interruption, just clean, deliberate surfaces in warm 18ct pink gold. Snap up this wonderful vintage gem and add it to your collection today!

Piaget was founded in 1874 in the small Swiss village of La Côte-aux-Fées. Georges-Édouard Piaget had a passion for watches from a young age. He created movements from his workshop. It wasn’t until his son Timothée Piaget took over that the business saw a huge expansion, building a new manufacturing facility. In 1943, Piaget became a registered trademark. Creating ultra-thin watches with their 9P Calibre, which was an incredible 2mm thick, a world record that they still hold. Today, Piaget is a subsidiary of the Swiss Richemont group. This group includes Cartier, Van Cleef & Arpels, IWC Schaffhausen, Panerai, Vacheron Constantin, Montblanc, Dunhill, and Chloé.
