If you're unsure about getting this because of the date but your dial doesn't have one, don't worry, it'll just mean you have three setting on your dial vs two (wind, date, and time adjustment) — otherwise, it'll work great
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.
