CONSTANT FORCE TOURBILLON
TRIFOLD APPROACH TO CHRONOMETRY
Its historical roots, aesthetics and real-beating seconds tie the Arnold & Son Constant Force Tourbillon to the tradition of ultra-precise marine chronometers. Actual beat seconds are a result of this mechanism. As the constant force system reloads 60 times per minute, it is possible to view a second jumping from marker to marker by attaching a hand to the winding wheel. Despite the common feature of quartz watches, it is a rare achievement in mechanical watches.
