ETA SA 6325

The ETA caliber 6325 is a manual-wind mechanical movement measuring 29mm in diameter with a frequency of 21,600 vph. It features Incabloc shock protection and is typically found with 17 or 21 jewels. The movement includes a small seconds subdial at 6:00 and is considered a smaller version of the ETA/Unitas caliber 6498-1, sharing the same architecture but differing in dimensions, beat rate, and lift angle. Often referred to as a Wehrmachtswerk, it appeared in vintage military watches from brands such as BWG Swiss Courage and Cortebert. Production has been discontinued.
