Similar to the 6138A, minor modifications were made to the switching mechanism. An old archive entry mentions a sample with 17 jewels, although it is uncertain whether the rotor bridge was swapped. The movement showcases a range of functions, including a 60-second, 30-minute, and 12-hour chronograph with a pillar wheel, a quickset day display available in two languages, a quickset date display, as well as automatic operation.
