Seiko [SII] NH35a (Date Only) Automatic Movement: California [Full Luminous]


Building the watch of your dreams starts with the entirely mechanical in-house Japanese Seiko NH35a 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.

Genuine Seiko NH35a Automatic Movement with Date at 3 or 4 O'Clock, depending on the orientation of the watch case. Perfect for dials with a date-only window. This NH35a movement is special, with a professionally pre-installed aftermarket luminous date wheel. The term "California" describes the thick layer of C3 or BGW9 luminous material that is thoughtfully applied to the entirety of the date wheel.

Comes supplied with watch stem.

[C3 Luminous]: Applied green C3 lume.

[BGW9 Luminous]: Applied blue BGW9 lume.
