Cartier Ballon Bleu de Cartier Ladies Watch Automatic Yellow Gold Diamond Bezel 33mm Silver Dial Alligator Leather Strap WJBB0040 - BRAND NEW

The Cartier Ballon Bleu de Cartier is one of the most celebrated watch designs of the twenty-first century, introduced by the Maison Cartier and immediately recognized for its signature floating crown nestled within a graceful arc of the case flank. The rounded, bubble-like case silhouette gave the collection its evocative name—Ballon Bleu, French for blue balloon—and the design has become a cornerstone of Cartier's contemporary identity alongside storied classics such as the Santos and the Tank. Reference WJBB0040 represents the collection in its most opulent expression, tailored specifically for the discerning woman who values both artistry and wearability.

The 33mm case size is the quintessential ladies' proportion within the Ballon Bleu lineup, generous enough to register with presence on the wrist yet refined enough to sit comfortably beneath a cuff or beside a bracelet stack. Crafted entirely in 18k yellow gold, the case glows with a warmth that perfectly complements the silver Roman numeral dial within. Yellow gold has been central to Cartier's jewelry-watchmaking tradition for well over a century, and its use here connects this modern reference directly to the maison's storied Parisian heritage.

The diamond-set bezel is the defining flourish of WJBB0040, encircling the dial with a continuous parade of brilliant-cut stones that catch light from every angle. This is watchmaking that functions simultaneously as fine jewelry, a duality that Cartier pioneered and continues to execute with unmatched authority. The silver Roman numeral dial is quintessentially Cartier—clean, legible, and steeped in the typographic language the maison has used across its most iconic timepieces for generations. The blued-steel sword hands glide over the chapter ring with an elegant sweep that underscores the watch's automatic movement within.

The alligator leather strap completes the aesthetic with supple texture and a quiet luxury that never competes with the case and dial. Alligator leather has long been the material of choice for Cartier's most elevated strap offerings, valued for its natural grain pattern, durability, and the way it softens gracefully with wear. Paired with an 18k yellow gold deployant or folding clasp, the strap secures the watch with the same attention to detail found in every other element of the reference.
