Building the watch of your dreams starts with the in-house Japanese Seiko NH36a movement. This movement is one of the most trusted choices for watchmakers everywhere, dominating all comparable movements in its price range in terms of quality, reliability and performance. It is based off the famous Seiko 7S26 movement, upgraded with modern hacking and hand-winding capabilities.

All parts available in our store are designed around this iconic movement - this is the foundation of your custom watch build here at Watchdog Supply.

This purchase includes the professional assembly of your watch build. Every custom watch we assemble is pressure tested to 200m (~660 ft.) before it is thoughtfully packaged and shipped.


This includes:

  • 1x Seiko NH36a Movement.
  • Service, Professional Assembly.
  • One Free Handmade Genuine Leather Strap of Choice. (Reduces to FREE in Cart.)
