Cartier unveiled the Ballon Bleu in 2007 at the Salon International de la Haute Horlogerie in Geneva, and it quickly became one of the Maison's three commercial pillars alongside the Tank and the Santos. Where those icons are angular and geometric, the Ballon Bleu is defined by roundness: a smooth, pebble-like convex case whose most distinctive feature is the crown. The fluted crown, set with a blue cabochon, is tucked under a protective arch that sweeps across the case flank and presses a gentle "dent" into the edge of the dial. That floating blue stone gives the watch its name — "Blue Balloon" — and is the single design cue collectors recognise instantly.
The crown stone is one of the model's most discussed details. Higher-end and precious-metal references can use a natural blue sapphire cabochon, while many steel and quartz references use a synthetic spinel of the same blue; both are period-correct, and the choice depends on the exact reference and tier. The dial language is pure Cartier: Roman numerals, a chemin-de-fer minute track, and blued sword-shaped hands, with a date window typically at 3 o'clock on automatic models.
The collection was conceived to span the whole wrist. Cartier built it across roughly 28mm, 33mm, 36mm, 40mm, 42mm and 44–46mm sizes, in stainless steel, two-tone, and yellow, rose and white gold, with quartz, automatic and chronograph variants. The 42mm steel automatic — references such as W69012Z4 and the black-dial W6920042, both powered by the automatic caliber 049 — became the definitive men's Ballon Bleu, while the smaller 28mm and 33mm sizes have always been favourites for women and slimmer wrists. The 44mm W6920077 XL chronograph served the sportier buyer before being discontinued, and the line has stretched all the way up to a flying-tourbillon complication and fully diamond-set pieces.
From 2007 onward Cartier used the long "W"-prefix references (the W692 family signals Ballon Bleu), later migrating much of the catalogue to the current WSBB and WGBB naming. Today the WSBB0049 (42mm steel) and WSBB0044 (33mm steel) carry the line forward with silvered guilloche dials and interchangeable bracelets. The Ballon Bleu won early design recognition, including watch-of-the-year honours in 2009, and remains one of the most widely worn luxury watches in the world.
Collectors are drawn to it because it delivers unmistakable Cartier elegance in a comfortable round case, with a deep menu of sizes, metals and movements that suits men and women alike — a genuine "his and hers" icon.
