Seiko spare part 383611 (1 piece) – Setting lever with axle for caliber 6109A / 6119A / 6139B – NOS

Original Seiko spare part 383611 from unused old stock (NOS).
This is the setting lever with axle , a central component of the key mechanism that controls the switching function between winding and hand setting.
This part is suitable for the Seiko automatic movements 6109A , 6119A and 6139B , which are among the classic Seiko calibers of the late 1960s and 1970s.

The setting lever is unused, in excellent condition and in high demand, as original parts for these movements are becoming increasingly difficult to find – especially for the 6139 chronograph series.
