For all the visual appeal, this is where Grand Seiko really deserves the most applause. An unwinding mainspring barrel normally applies link less link torque as the link reserves are depleted, supplying less power to the oscillator and less amplitude, which in turn means the watch will beat faster. Grand Seiko fixes this problem with a remontoir – a spring that acts buffer to even out that torque to move that energy to the tourbillon regulator directly.
