The Tutima Caliber 320 is a modified ETA Valjoux 7750 automatic chronograph movement used in the Grand Flieger Classic Chronograph. Tutima has customized the rotor with their signature gold seal and the movement has been meticulously regulated to achieve German Chronometer certification (DIN 8319), which is in some regards more stringent than COSC. The cam-actuated chronograph features the classic 6-9-12 subdial layout. This caliber powers Tutima's modern interpretations of their legendary 1941 Flieger chronograph.
