I was really impressed with the speed the movement was shipped and arrived, it was well packed, it looks great and should look better than the white version I have.

NH36 regulated

I have number of Seiko watches and have over the years purchased number of NH36 movements to replace original 7Sxx movements. I hate no hacking functions. Movements arrived double quick time (I’m in Australia). I wound them up and put them on time grapher. Both movements met the 0+8 second spec. I was bit surprised with the beat error at 1 msc than again I’m not a professional. Gray service. Have bought stuff before.

NH36 Black movement

Looks great. I’m only using the date onto a Black Dial. The date number really stands out.
