Collectors target this reference for its 38mm 18k yellow gold case featuring traditional coin-edge fluting and straight lugs with screw-down bars. The watch utilizes the manual-wind Caliber 533.2, which is based on the Lemania 2310 ebauche, finished with hand-engraved bridges visible through a sapphire caseback. The solid gold dial is finished with hand-turned engine guilloché, featuring distinct patterns for the sub-dials and the main chapter ring. On the secondary market, this reference typically trades between $35,000 and $50,000 depending on the presence of original accessories. While the yellow gold version is the most common, a limited number of examples were produced in platinum, which command a significant premium at international auctions due to their lower production volume."}, "listing_stats": {"count": 0, "median": 0, "low": 0, "high": 0}, "listings": [], "auction_lots": [{"slug": "breguet-3610-2025", "brand": "Breguet", "reference": "3610", "model": "Perpetual Calendar Chronograph", "case_material": "18k Yellow Gold", "hammer_usd": 64115, "year_sold": 2025, "venue": "Phillips Geneva", "lot_summary": "An obscure and rare reference from the early 1990s featuring a Lemania-based movement and distinctive officier lugs.", "source_url": "https://www.phillips.com/detail/breguet/CH080125/202", "provenance": "ai_generated_grounded", "url": "https://mostexpensivewatches.net/auctions/breguet-3610-2025"}]}
