MECHANICAL-QUARTZ HYBRID
The Flygraf French Air and Space Force is powered by a Seiko VK64 Mechanical-Quartz hybrid caliber. The time measurement complication is operated by a quartz movement while the chronograph's hand is controlled by a mechanical module that ticks multiple times per second, perceived by the eyes as a sweeping motion.

Die Abmessungen sind ja auch noch im Rahmen.

Durchmesser: 41 mm
