Produced in the 1940s and powered by the reliable Landeron 13 movement, this elegant 18K pink gold chronograph bears the distinctive Tiffany NY signature on its black gilt dial. Such double-signed pieces were retailed through Tiffany’s flagship in New York and represent the transatlantic reach of Swiss watchmaking during that period. Beyond its rarity, this example captures a key moment in Heuer’s history — when the manufacture’s chronographs began to attract discerning international clients and appear in the world’s most exclusive retail windows. The combination of Tiffany provenance, Heuer’s early chronograph expertise, and the refined aesthetics of the Landeron 13 calibre make this watch an exceptional collector’s piece, a testament to both technical craftsmanship and the elegance of mid-century luxury.
