The new Blancpain Grande Double Sonnerie is a landmark achievement in watchmaking, but it comes with a landmark price: 1.7 million CHF. For the discerning buyer, this raises a critical question: beyond the technical brilliance and world-first accolades, does this timepiece offer genuine value in the ultra-high-end market? Let’s break it down.
The Verdict: An Honest Breakdown
When evaluating a watch at this level, traditional value metrics don’t apply. Instead, we look at innovation, execution, and exclusivity.
Pros:
- Horological First: It is the world’s only dual-melody grand sonnerie wristwatch, allowing the user to switch between the classic Westminster Quarters and a unique Blancpain melody.
- Integrated Engineering: Unlike many competitors who use modules, its perpetual calendar and flying tourbillon are fully integrated. This allows for a surprisingly wearable 14.5mm thickness and a stunningly openworked view of the movement.
- Acoustic Perfection: The use of gold for the case, mainplate, and even the gongs creates a unified material for superior sound transmission and clarity.
Cons:
- Astronomical Cost: The price places it in a category of its own, making it inaccessible to all but a tiny fraction of collectors.
- Power Demands: The grand sonnerie function has a separate power reserve of only 12-14 hours, requiring diligent winding to enjoy its main feature.
- Extreme Scarcity: With only two pieces produced annually, ownership is less a matter of money and more a matter of access.
Positioning in the Market
While other elite brands produce grand sonneries, none have successfully integrated two selectable melodies into a single wristwatch. This isn’t just an iterative improvement; it’s a unique selling proposition that sets Blancpain apart. Furthermore, its integrated perpetual calendar avoids the bulky, movement-obscuring modules common in other grand complications, positioning it as a more elegant and technically cohesive piece of engineering.
Final Recommendation: Who Should Buy This?
Let’s be clear: this is not a watch for the savvy shopper looking for a deal. The Blancpain Grande Double Sonnerie is for the pinnacle collector for whom price is secondary to historical significance. Its value lies not in daily wear but in its status as a groundbreaking piece of horological art. If you are a collector who seeks to own a “world’s first” and appreciate unparalleled mechanical innovation, this watch represents a worthy, if monumental, investment.
