Blancpain Defines Adventure: The Eight-year Journey of Creating the Innovative Grande Double Sonnerie

A wearable chiming wristwatch is considered to be one of the most complex creations in the watchmaking industry, and Blancpain has taken this intricate artistry to new and groundbreaking heights with the Grande Double Sonnerie. This exceptional timepiece, under development for a whopping eight years, is fluidly integrated with inventive mechanisms and sophisticated specifications, boasting 21 new patents. It is, without doubt, the epitome of Blancpain’s exceptional craftsmanship and relentless innovation.

However, that’s not where the beauty of this timepiece ends. Blancpain further personalizes the experience for its discerning clientele by offering the possibility of a fully customized melody and tailored case and movement materials and finishing. Last, but certainly not least, its spectacular complications include a Grand and Petite Sonnerie minute repeater and dual melodies, all user-selectable, a retrograde perpetual calendar, and dual rear power reserve indicators.

The standout feature is, of course, its melodic chiming system. A minute repeater strikes hours, quarters and minutes on demand, while a petite sonnerie does so automatically, striking the hours and sometimes the quarters but not repeating the hours each quarter. A grande sonnerie, as the name fittingly suggests, chimes both the hours and quarter-hours as time passes. Every 15 minutes, the watch sings the time seamlessly, rendering the Grande Double Sonnerie not just a watch, but a symphony on the wrist.
