Cartier Tank Cintrée
Generally less collectible than men's watches, some women's models, such as vintage Cartiers, have appreciated significantly in the past decade. "The Tank Cintrée is a beautiful ladies' watch with potential for growth still," says Schaerer. A yellow-gold Tank sold for $20,000 ten years ago, but Schaerer estimates it would be closer to $40,000 today. The platinum version went for $40,000 in 1995 but made $250,000 last year.
