Works wonderfully

I had this project in mind for a long time to create a gold skeleton watch with an ordinary case. This movement worked wonderfully and able to get the spacer ring on easily and works wonderfully keeping good time.

NH35 - first love

As a movement for my first build, I was really happy with how easy it is to use and it works great!

Un bon mouvement fiable et compatible avec les accessoires Namoki

Alexandre C. (Deurne, BE)
Beautiful movement but exclusive grey spacer

It's a great looking skeletonized movement.
Be aware, it does not come with a grey spacer like the other Seiko movements NH35, NH36,... So don't forget to buy it separetely.
