Think you know luxury watches? Blancpain just dropped a masterpiece that redefines what a grand complication can be, and the hidden details are absolutely wild.
5 Mind-Blowing Facts About the Blancpain Grande Double Sonnerie
1. It Has a Rockstar’s Touch
You read that right. One of the watch’s two selectable melodies was developed in collaboration with a rock legend: Eric Singer, the former drummer of the iconic band KISS. He worked with Blancpain to create a unique “Blancpain melody” that uses the same notes as the classic Westminster Quarters but in a completely new sequence. It’s a collaboration you’d never expect in the world of high horology.
2. It’s the First Watch of Its Kind
This isn’t just another chiming watch. The Grande Double Sonnerie is the world’s first grand sonnerie wristwatch to feature two distinct, selectable melodies. The wearer can switch between the traditional Westminster Quarters and the new rock-inspired Blancpain melody with the press of a button, a technical feat that has never been accomplished before.
3. The Sound is Literally Golden
To achieve the perfect chime, Blancpain’s watchmakers tested 11 different materials for the gongs, including steel and bronze. The winner? Gold. They discovered that gold produced the richest, clearest tone. This decision was so crucial that it influenced the entire construction, leading to a case, mainplate, and bridges also made of gold to ensure perfect sound transmission.
4. You Can Ditch the Special Tools
Ultra-complicated watches, especially perpetual calendars, usually require a special stylus or tool to make adjustments, which can be a hassle. Blancpain engineered a clever solution. This watch features unique correctors hidden beneath the lugs, allowing the owner to set every calendar function with just a fingertip. It’s a surprisingly user-friendly feature on a monumentally complex machine.
5. A Secret Signature You’ll Never See
Only two of these watches are made per year, and a single master watchmaker spends an entire year building one from start to finish. As a final, personal touch, that watchmaker engraves their name on the reverse side of a plate on the dial. This signature is completely hidden from view once the watch is assembled—a secret mark of the artist for what is truly a masterpiece.
From rock and roll collaborations to hidden signatures, the Blancpain Grande Double Sonnerie is more than a timepiece; it’s a collection of incredible stories packed into a wearable work of art. It truly sets a new standard for what’s possible.
