Brilliant Skeleton Northern Lights (Reference BS431.40.RD.QR.A) was introduced around 2014 as a limited production model within the brand’s high-jewelry skeleton collection. Collectors target this reference for its 44mm 18k rose gold case set with 251 round diamonds and its open-worked JCAM01 caliber, which features a 46-hour power reserve. A defining technical characteristic is the use of a red mineral crystal dial that provides a translucent view of the hand-finished movement architecture. Production was limited to 101 pieces globally, making it a rare find on the secondary market where it typically commands prices between $35,000 and $55,000 depending on condition. While the rose gold and red crystal version is the primary reference, a notable variant exists in stainless steel with a blue mineral crystal, which often appears at lower price points in the secondary luxury market.", "score": 198}, {"slug": "audemars-piguet-15210bc-code-11-59-selfwinding", "brand": "Audemars Piguet", "ref": "15210BC.OO.A002KB.01", "model": "Code 11.59 Selfwinding", "case_material": "18k White Gold", "url": "https://mostexpensivewatches.net/reference/audemars-piguet-15210bc-code-11-59-selfwinding", "description": "The Audemars Piguet Code 11.59 Selfwinding reference 15210BC.OO.A002KB.01 was introduced in 2019 as part of the collection’s initial launch and remains in production.

Collectors monitor this reference as a foundational piece of the brand’s modern non-Royal Oak strategy. On the secondary market, this specific model typically trades between $22,000 and $28,000, representing a significant depreciation from its original retail price.
