Movement is easy to work with and the $15 extra to get it regulated was worth it. Keeps accurate time and works well in my watch. Pic is from "Watch Accuracy Meter" app so take it with a grain of salt, but this regulated NH35 outperforms the way my Seiko SRPD (with the Seiko version of the NH36) was regulated from factory by a wide margin!
What can you say about the NH movements? Solid and reliable workhorses that can take a beating. With the help of a timegrapher they can be adjusted easily and acceptably, which makes them a reliable component in several of my self-built watches. As usual, they arrive well packaged at Namokimods and are equipped with a plastic adjustment ring and a custom-made stem.
I bought the regulated movement and am impressed with how accurate that it is. Well worth the extra money.
as planned,a real NH
a very reliable workhorse to power your watch no matter what ... and for ages!!!
