Buying a pre-owned Cartier Ballon Bleu — FAQs
Is the Ballon Bleu unisex?
Largely yes - its rounded case and range of sizes mean smaller models suit slimmer wrists while larger sizes work well for men, making it a popular choice across the board.
What is the blue stone on the crown?
It is a sapphire cabochon, a signature Cartier detail set into the crown and shielded by the case's protective guard, which is part of the model's identity.
Quartz or automatic?
Smaller sizes are usually quartz for slimness and low maintenance, while larger models often house automatic movements; choose based on size preference and whether you want a mechanical watch.
