The Chronomètre Bleu, which collectors often call 'CB', has become a cult favorite in modern independent watchmaking. Its appeal lies in the striking combination of an unconventional case material and a highly distinctive dial, setting it apart as one of the most recognisable creations of modern horology.
The case is crafted from tantalum, a rare metal distinguished by its unique blue-grey hue. Rarely used in watchmaking due to the extreme difficulty of machining it, tantalum requires exceptionally high temperatures to be shaped and finished. Once mastered, however, it offers remarkable durability and outstanding resistance to corrosion, contributing both to the watch’s technical appeal and its singular aesthetic.
