Seiko (SII) NH72 Automatic Movement - Skeleton Ruthenium Grey

Options
Genuine SEIKO NH72 Movement. A skeleton display with Côtes de Genève decorated rotor.

The TOP choice for movement swap with a complete view of the movement from the watch face. Appreciating the beauty and intricacy of a mechanical movement.

  1. REGULATED
    Hugely improved on the accuracy! These are regulated by certified watchmakers from 0 to +8 seconds per day.
