Cal 328 and it’s more common sisters 327 & 329 share many features and parts with the 520 original lady Curvex caliber. 328 has unique parts, including conical escape pivots.

This example ca1937, stamped “328”. From the works & “last 4” digit dial side sn marking, the 328 was probably built by Aegler (formerly Factory A). It seems to be the next baguette evolution from the 879. I note only 1 master book model with the 328, and it used the 111 style number originally held by the 879. I do not yet have a 327 or 329 to compare markings.
