The Cartier Ballon Bleu de Cartier Ref. W2BB0039 (Two-Tone 42mm) is one of Cartier’s most recognizable modern designs, blending classic Parisian elegance with a subtle sport-lux presence. Introduced as part of the Ballon Bleu collection (launched in 2007), this model features a 42 mm case in stainless steel and 18k yellow gold, giving it that signature two-tone (bi-metal) look that feels both timeless and slightly more elevated than full steel.

The defining design element is the integrated crown with blue cabochon spinel, recessed into the case flank—creating the illusion of a “floating” crown and giving the watch its distinctive rounded silhouette. The dial is pure Cartier: a silvered guilloché pattern with bold black Roman numerals and blued steel sword hands, paired with a date window at 3 o’clock. The overall look is elegant but still versatile enough to wear casually, especially on the steel/gold bracelet.

Inside, the watch is powered by the Cartier Calibre 1847 MC automatic movement, offering reliable everyday performance with a focus on durability and anti-magnetic resistance. It’s protected by a sapphire crystal and rated to about 30 m water resistance, reinforcing its role as a luxury everyday watch rather than a tool piece.

History of Cartier

Cartier, founded in Paris in 1847 by Louis-François Cartier, began as a jewelry workshop that quickly gained recognition among French aristocracy. Under the leadership of Alfred Cartier, the company expanded into watchmaking, with a pivotal moment occurring in 1904 when Louis Cartier created the Santos Dumont, the world's first modern men's wristwatch, for aviation pioneer Alberto Santos-Dumont.

Throughout the 20th century, Cartier continued to innovate in watch design, introducing iconic timepieces like the Tank in 1918, inspired by the Renault FT-17 tank. The company's watches became known for blending functionality with artistic elements, incorporating Art Deco influences and precious materials. Today, as part of the Richemont Group, Cartier remains a leader in luxury watchmaking, continuing to produce exquisite timepieces that combine tradition with contemporary design, from the classic Tank to the modern Pasha.
