Customer Reviews
I picked up this Miyota 9015 from Namoki at the beginning of this year. This is my first build with the movement and I was a bit worried about using it versus the NH series. I was very happy when I got to building to see how straight forward it was. The movement came running within spec from the factory. Mine sits at about +10 seconds per day which is well within spec. During the build, I definitely made some slips and beat on this movement but it kept running perfectly.
I would highly recommend building with this movement. Disclaimer for my build, I have a custom movement holder to fit the SRPE case but aside from that, the movement is great.
The finishing and operation of the 9015 movement is definitely a few levels above the NH35. It is not as user friendly as the NH35 though and I would only recommend for more experienced builders
