DIY Watch Club - Tailor-made CNC-machined Watch Screwdrivers for Miyota 8 series & Seiko/TMI NH Rotor

A tailor-made CNC-machined screwdriver designed for screwing and unscrewing automatic rotor for Miyota 8 series and Seiko NH35 movement. Miyota 9 series (9015, 9029, 9039 90S5, 9075 ... etc) will require different screw drivers. We recommend 100

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.

Use case:

• Installing custom rotor
• Fix loose rotor

Key specs:

• CNC-machined precision tip for perfect grip.
• Tip width: 2.5mm
• Tip thickness engineered to fit Miyota and Seiko rotor screw slot
• Anti-slip handle
• Ergonomic top end for easier application of force
• Ball-bearing equipped for better tactile feedback on the resistance when tightening the screw. Prevents over-tightening 
• Replaceable tip
