Overview
The Cartier Ballon Bleu 36 Automatic (ref. W69011Z4) represents the mid-size iteration of one of Cartier's most celebrated modern introductions. Housed in a 36.6 mm stainless steel case, it pairs a self-winding movement with a silvered guilloché dial dressed in Roman numerals — a combination that firmly places it in the dress-watch tradition. The characteristic sapphire-set crown nestled within the case flank remains the silhouette's most recognisable design signature.
History
The Ballon Bleu line debuted in 2007, immediately drawing attention for its distinctive rounded case and the blue sapphire cabochon integrated into the crown guard — a detail that gave the collection its name. Reference W69011Z4 was part of the inaugural generation and remained in production through 2021, making it one of the longer-running configurations in the line. Its 36.6 mm diameter positioned it as a versatile choice that sat comfortably between the smaller and larger Ballon Bleu offerings, attracting both men and women collectors over its production life.
