What is the Seiko NH36 Movement Kit?

The Seiko NH36 movement is a mechanical, self-winding movement that includes a date function and a hacking feature. It is designed for use in wristwatches and is especially popular among watchmakers who prefer hands-on watch assembly.

Key Features of the Seiko NH36 Movement
