GRAHAM was determined to preserve the long-standing tradition of high precision English timepieces from the Age of Enlightment even though the tourbillon hadn’t yet been. The 60 seconds tourbillon was created incorporating high-technology and expert craftsmen, such as local partner Le Cercle des Horlogers in La Chaux-deFonds, has contributed to achieving the classical Geo.Graham Tourbillon.

The double-bridge construction of the 60-second tourbillon, at 6 o’clock, combined with the microrotor movement provide the perfect functional balance with an increased power output and barrel resetting as well as enabling to reduce thickness.

Made in pink gold (18K), the Geo.Graham Tourbillon features remarkable elements such as the balance wheel and off-centred oscillating weight which together create a dynamic effect and perfect unity of technology and design.
