This reference is distinguished by its white dial and white registers, a departure from the standard \"Siffert\" model which features black sub-dials. It utilizes the Calibre 12 automatic chronograph movement housed in a 42mm stainless steel cushion case with a notched bezel. Collectors value this variant due to its extreme rarity; it is estimated that fewer than ten authentic examples are publicly known to exist. Because of this scarcity, secondary market prices typically occupy the high-five-figure to low-six-figure range depending on condition and provenance. A notable auction result occurred in 2017 at the Heuer Parade sale, where an example achieved a hammer price of approximately 81,250 CHF. Verification of the serial number range, typically around 242xxx, is a critical factor for collectors evaluating the authenticity of this specific execution.", "score": 200}]}
