The most complex Greubel Forsey creation to date. The Grande Sonnerie is undoubtedly one of the greatest horological complications. Right from the beginning of their partnership, Robert Greubel and Stephen Forsey began reflecting on what their own resolutely contemporary vision of this regal complication might be.

For eleven years, the Grande Sonnerie set the cadence of their day-to-day lives, as they worked in the utmost secrecy to assemble the 935 components of this timepiece, and above all to ensure absolute harmony between the movement, the exterior and the acoustics.

Its ergonomics guarantee unparalleled intuitive ease of use. To ensure optimal architectural balance, obsessive attention to detail was devoted to the intelligent integration of the most important mechanisms and indications (tourbillon, cathedral)

Limited 3 pieces per year
