Collectors target this reference for its manual-wind Calibre 876-440B, which integrates a perpetual calendar with an eight-day power reserve. The 40mm case is constructed from 950 platinum, distinguished by a silvered sunray dial featuring a red security indicator that warns against adjusting the calendar during specific hours. This reference is noted for its high horizontal density of complications, including a moon phase and power reserve indicator, while maintaining a relatively slim profile. On the secondary market, this platinum model typically trades between $25,000 and $35,000 depending on condition and the presence of original accessories. A notable production detail is the limited nature of the platinum variant compared to the more common pink gold reference Q1612420, making it a rarer find at auction."}, "listing_stats": {"count": 0, "median": 0, "low": 0, "high": 0}, "listings": [], "auction_lots": [{"slug": "jaeger-lecoultre-q161642a-2018", "brand": "Jaeger-LeCoultre", "reference": "Q161642A", "model": "Master Eight Days Perpetual", "case_material": "Platinum", "hammer_usd": 37500, "year_sold": 2018, "venue": "Phillips Hong Kong", "lot_summary": "A limited edition perpetual calendar with an 8-day power reserve, featuring a striking skeletonized dial.", "source_url": "https://www.phillips.com/detail/jaeger-lecoultre/HK080218/912", "provenance": "ai_generated_grounded", "url": "https://mostexpensivewatches.net/auctions/jaeger-lecoultre-q161642a-2018"}]}
