The Junghans J38A/1 watch movement was produced during 1894-1895, with a total of 7000 units manufactured. It features a hunter calibre and is classified as model 3. The movement incorporates a bimetallic screw balance and utilizes a ratchet between plates in conjunction with a crown mechanism equipped with a rocker bar. This design effectively prevents the hands from moving when switching between setting and winding, addressing a common issue associated with rocker clutches. The movement's functions include stem winding and lever setting, as well as a sub-second display.
