Collectors prioritize this reference for its 37.5mm stainless steel step-bezel case and the inclusion of the caliber 13ZN, a manual-wind movement featuring an integrated flyback complication. The reference is noted for its waterproof-style case construction, often featuring round \"mushroom\" pushers and a screw-down case back. Dials typically feature multi-scale configurations, including tachymeter and telemeter tracks. Due to its rarity and technical significance, secondary market prices generally fall within the $60,000 to $120,000 range, though exceptional examples can exceed these figures. A notable auction result occurred in 2017 when a stainless steel 5415 with a silvered dial sold for approximately $140,000. Production numbers for this specific reference were limited, making well-preserved, unpolished steel examples difficult to source in the current vintage market.", "score": 199}]}
