NH Movement Rotor - Côtes de Genève - Gunmetal

The Côtes de Genève motif is the best known of all the decorations adorning watch movements. Perhaps this is due to its name that initially seems both striking and somewhat strange, or possibly because it is so strongly present on movements. Whatever the case, this pattern traced on the smooth surfaces of mechanical (and indeed quartz) movements is a familiar sight on the watchmaking scene - to the point where one almost forgets that finishes are not a purely aesthetic element.

Here is a NH movement rotor, Côtes de Genève in Gunmetal.

With a sapphire caseback, it is all the reason to beautify the movement and improving the aesthetic. Furthermore, this is a simple and easy mod that requires just screwing and unscrewing of the rotor screw.

  • 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.

Came with a screwdriver too. Easy to install, fit the movement perfectly even though I had a custom bridge installed
