Collectors prioritize this reference for its balanced aesthetic and the use of high-grade movements, primarily the Valjoux-based Caliber 434 or the earlier Caliber 492. While the model was manufactured in yellow gold, rose gold, and steel-and-gold configurations, the stainless steel variant is the rarest, with fewer than 300 units estimated to have been produced across the entire production run. Dial variations include pulsometric or tachymetric scales and sector layouts. On the secondary market, stainless steel examples typically command between $40,000 and $100,000 depending on condition and dial rarity. A notable auction result occurred in 2022 when a steel example with a silvered sector dial sold for approximately $163,000, reflecting the premium placed on well-preserved steel specimens.", "score": 199}]}
