Junghans J880.4

The J880.4 is an automatic chronograph movement manufactured by Junghans. Based on the ETA 7750, it features a 38-hour power reserve, a stop function, and subdials for 30-minute counter and small seconds. The movement is not in-house, relying instead on the well-established Valjoux architecture. It remains in production and powers the Meister chronograph collection.
