Tourbillon Pura

Asaoka pursuits purity of Tourbillon watch by creating Tourbillon Pura. The appearance of Pura is literally simple regarding both the dial side and back side. Pura has the movement structure that one plate holds whole movement parts and it maximizes the positioning of parts accurate and optimized. The tourbillon carriage was made from A7075 duralumin that has relatively low specific weight but strong and utilized in aerospace industry and rifle. Hajime Asaoka uses this material to keep durability and high timing accuracy by maximizing amplitude of balance not to overspend torque from mainspring by rotating carriage.
