The Seiko NH38 movement is the unbranded version of the Seiko 4R38 movement. Seikos NH38 movement is based off of the NH36 and is identical in size and includes hacking, hand winding, and a 41 hour power reserve. The NH38 is perfect for openheart dials, and dateless dials in order to avoid the phantom date change. Seikos NH38 Movement is known for being a work horse, and is the perfect movement to use in a build that will be passed down generation after generation. Hacking, handwinding, and the pure reliability of the NH38 will make this the perfect movement for your next modded Seiko, or even to build a watch from scratch! The NH38 movement will fit all the cases sold on Watch-Modz.
