  "original_price": "~$2,500 (Historical Retail)",
  "verdict": "Good Deal",
  "analysis": "The asking price of $899 is very competitive for a Cartier Must 21, specifically Reference 1330, especially since the seller claims to have the original papers. This model typically sells on platforms like eBay, Chrono24, or The RealReal for between $1,000 and $1,500 depending on condition. The photos show some scratching on the bezel (common for this model), which validates the 'used' status but may downgrade it from 'excellent' to 'very good'. The fact that the ad has been up for 5 months but recently updated suggests the seller is motivated and likely negotiable, though buyers must verify authenticity in person.",
