Théo Auffret’s Tourbillon Grand Sport gives traditional mechanics a contemporary frame

The Tourbillon Grand Sport moves Théo Auffret’s work into a more contemporary case, with an integrated strap connection and a concave profile. A sapphire chapter ring leaves the movement exposed, while central hours and minutes replace the regulator arrangement of his earlier watch. The tourbillon carries the seconds hand.

An arched indication shows remaining torque, rather than simply counting hours of reserve. The hand-wound movement runs for approximately 50 hours. The 2022 launch coverage shows a steel prototype and specifies titanium for the four-piece subscription production series. Both photographs here depict that prototype; its case measures 41mm across and 13mm high.
