Greubel Forsey Grande Sonnerie 43.5

The Greubel Forsey Grande Sonnerie is a remarkable expression of contemporary haute horlogerie, presented in a 43.5mm titanium case and powered by a manual wind movement. Its round architecture and sapphire crystal case back underscore the maison’s uncompromising approach to mechanical artistry, offering a view into a watch conceived for the most discerning collector. A black dial with index hour markers gives the composition a measured, modern presence, balancing visual restraint with technical gravitas. Paired with an alligator strap and secured by a folding buckle, the watch wears with refinement and comfort, while 30 meters of water resistance adds a practical note to its rarefied character. True to its name, the Grande Sonnerie occupies an exalted place within watchmaking, uniting acoustic complexity with Greubel Forsey’s celebrated devotion to hand-finishing, innovation, and architectural movement design. It is a timepiece that speaks not only to precision, but to the pursuit of mechanical excellence as an art form.
