NH35A movement

It's a good movement running at accurate time.

Excelent movement

I bought this movement to replace a damaged one in my king turtle. The black day date wheel makes a significant upgrade to the visuals and it keeps fantastic time straight out of the box. My watch is now running between 0 to plus 3 seconds a day. Previously it was running at least 1 minute slow a day. Couldn't be happier


It works and is on time!

NH 34 movement

As advertised, can’t beat the SII Seiko’s fair price at Namoki

Beautiful movement

This movement ticked all the boxes for my BB58 build. Paired with a gold Geneve rotor and sapphire case back it really makes the watch
