Dubai Watch Week 2025: Chopard Launches Its Most Complicated Chiming Watch To Date: L.U.C Grand Strike – The Sound of Eternity

From the workshops of Chopard Manufacture comes the new L.U.C Grand Strike, an opus of mechanical mastery developed entirely within the walls of the Swiss watchmaker. This exceptional chiming timepiece, featuring a grande sonnerie, petite sonnerie and minute repeater with proprietary sapphire crystal gongs, represents the culmination of the Maison’s mechanical expertise and a decades-long sonnerie journey initiated by Karl-Friedrich Scheufele, Co-President of Chopard.

The result of over 11,000 hours of focused research and development, the L.U.C Grand Strike draws on ten proprietary technical patents - five of which were newly developed for this timepiece - making it the most complex watch ever created by Chopard Manufacture. Its performance is assured by rigorous in-house tests as well as certifying bodies such as the Poinçon de Genève, and the Contrôle Officiel Suisse des Chronomètres (COSC). With these certifications, the L.U.C Grand Strike is officially the most comprehensively rated grande sonnerie in contemporary high complications.
