This replica ballon bleu gbb0017 blue arrives in a 42mm case that places it firmly in the men’s territory of the Ballon Bleu de Cartier catalog. The WGBB0017 reference features a blue sunburst dial paired with a gold-tone case, creating a combination that reads significantly more formal than the standard steel variants. At 42mm, this is the largest standard diameter available in the collection, and the fully round case profile amplifies that presence compared to angular watches of similar dimensions. Cartier introduced the Ballon Bleu in 2007, and the larger men’s sizes arrived shortly after to meet demand beyond the original launch sizing.

Case & Movement Specs

• Case diameter: 42mm
• Case material: gold-tone finishing
• Dial: blue sunburst with painted Roman numerals
• Crown: blue synthetic spinel cabochon

The sunburst pattern on the blue dial creates a gradient effect that shifts between deep navy and lighter blue depending on the viewing angle. Roman numerals are printed directly on the dial surface and maintain the signature radiating arrangement.

Caliber Breakdown

An automatic movement handles timekeeping with a smooth sweeping seconds hand and quickset date function. The 42mm case provides ample internal volume, and winding occurs naturally through daily wrist motion. The blue dial on this version contrasts sharply with the silver dial WGBB0030 on rose gold, offering a bolder visual statement while sharing identical case geometry. The entire Ballon Bleu range uses the same lugless integration between case and bracelet regardless of material or size, maintaining design consistency across every reference.

How It Compares

Among 42mm Ballon Bleu options, the blue-and-gold pairing sits at the dressy end of the spectrum. Where steel models can transition into casual settings without effort, the gold-tone case and rich blue dial commit this reference to more elevated contexts. The rounded case shape softens the visual impact of 42mm, so despite the measurement it does not wear as large as a Santos or a pilot-style watch of similar diameter. If a blue dial with warm metallic accents is what you are after, this replica ballon bleu gbb0017 blue fills that position without reservation.
