Welcome! get started hereSeiko Mod Movements
High Quality NH34, NH35, NH36, NH38 Movements. Excellent manufacturing and High Reliability from the best sources. We use a third party company that we’ve been working with for many years to test the movements before sending them out. This is super important as many movements sit for long periods of time before being used. Our movements take a few extra days to send out in order to ensure they are functioning at spec or better. Ours may not be the cheapest, but they are the best.
Pricing: NH Movement prices have been steadily increasing throughout 2025, and supply has been decreasing. In order to continue offering these movements we’ve had to adjust the pricing. When prices come down we’ll adjust accordingly.
