The Cartier Ballon Bleu WSBB0040 is a modern watchmaking icon, celebrated for its unique pebble-like profile and “floating” aesthetic. This 40mm stainless steel model bridges the gap between classic horology and contemporary style, making it a versatile choice for both formal and daily wear.
The signature silvered guilloché dial is detailed with bold Roman numerals that curve around the integrated crown guard—a design hallmark of the Ballon Bleu collection. At the heart of this timepiece is the Manufacture Calibre 1847 MC, a high-performance automatic winding movement providing a 42-hour power reserve. Every detail reflects Cartier’s commitment to craftsmanship, from the fluted crown set with a synthetic blue cabochon spinel to the scratch-resistant sapphire crystal that ensures lasting clarity.
Designed for the modern lifestyle, the WSBB0040 features Cartier’s interchangeable bracelet system, allowing you to swap between the polished steel links and optional leather straps with ease. With water resistance up to 30 meters (100 feet), it is as durable as it is sophisticated, continuing to be a top-tier investment piece for luxury enthusiasts in 2025.

This timepiece has undergone a thorough inspection of water resistance, accuracy, functionality and condition to determine the level of reconditioning required to meet our strict standards. It has also been referenced against technical documents and manufacturer records where available to ensure authenticity and a clean history.
