  • To allow for CNC decoration, decorated rotor is 0.15mm thicker than SEIKO OEM rotor. Each and every rotors have been tested to fit all our bridges, cases and casebacks perfectly.

    Below is SEIKO's technical drawing , as long as the case and caseback intented to be use is designed with OEM specification as recommended by SEIKO, i.e. there is a 0.4mm gap between the rotor caseback, our rotor will fit just fine. In a scenario where these parts' dimensions deviate from SEIKO OEM, our rotors will be incompatible.

The quality is insane, very good product. DHL EXPRESS not even one week and I get my package. The packaging was also fine.

Beautiful rotor


Fantastic rotor. Really brings some bling to a pretty bland NH35 movement.
