  • 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.

Perfect Pop of Color

I added the blue skeletonized rotor to my subtly modded DressKX and it gives it the perfect little pop of color on the backside that I wanted. The quality of the rotor is excellent, and fitting it to the movement was easy and quick.

A little touch of blue

Very easy upgrade on a NH34 that give a touch of elegance to the movement. This rotor is very well made, in the spirit of GS.
Once again, Adriel's products are awesome. And its business is very serious. Buyers : don't hesitate a second.

Gorgeous colour and excellent quality

The rotor feels solid in the hand and the colour is fantastic. I don’t really notice the words on the rotor when I look at it in person and this is good for me.

It arrived a day before expected and was packaged phenomenally.

My favourite watch mod store because I know I can always trust the products and service.

Excellent alternative rotor. The color matches the blued screws I use.

Great quality, outstanding service

I purchased this rotor in order to modify a SNK615. Adriel shipped the order in order time and shipping might be managed in the best way I have seen.

The rotor is a very, very close resemblance to an actual GS rotor (which is really an achievement).

Lucius is the best supplier of mod parts I have seen and will keep doing business with them.
