A tailor-made CNC-machined screwdriver designed for screwing and unscrewing automatic rotor for Miyota 8 series and Seiko NH35 movement.
We specifically designed the screwdriver along with the CNC-machined tip to provide the best grip for Seiko automatic movements, as we know how painful it can be when we strip and scratch the ball bearings of the rotors of our favorite modded Seiko.
