Seiko Original Spare Part – Balance Staff – Seikosha (K.K.S.) Type 新8 [NEW 8] – NOS – (1 Piece)

Original Seiko/Seikosha replacement part from new old stock (NOS) – genuine balance staff, the central axis of the balance wheel.

The balance staff carries the balance wheel and hairspring, and its two fine pivots run in the movement's jewels. It is the most frequently broken component in a mechanical watch movement – the pivots typically break due to shocks or falls. This is precisely why a genuine NOS balance staff is a sought-after part for restorers; genuine Seiko NOS material of this kind is becoming increasingly rare on the market.

The staffs come from original Seikosha factory stock (packaging with red Seikosha "S" logo, manufacturer's abbreviation K.K.S. and factory-specific type designation 新8 - [New 8]). Seikosha was the manufacturing arm of the Seiko Group – the historical foundation behind the later Seiko and Grand Seiko movements.
