This specific reference is distinguished by its 46mm case constructed from 950 platinum and a midnight blue sunray-brushed dial. It houses the caliber 51613 automatic movement, featuring a seven-day power reserve and a perpetual calendar with a specialized moon phase display at 12 o'clock, which depicts the Little Prince standing on his planet. The exhibition case back reveals a 21-carat gold medallion on the rotor engraved with the same motif. At its 2013 auction debut, the watch sold for 173,000 CHF. Given its status as a unique piece, secondary market availability is non-existent, though its valuation remains in the mid-to-high six-figure range based on its historical significance as the first \"Le Petit Prince\" perpetual calendar."}, "listing_stats": {"count": 4, "median": 6600.0, "low": 5300.0, "high": 9750.0, "brands": 1, "merchants": 1}, "listings": [{"id": "h_8695738171571", "title":
