The Junghans 623 and the identically constructed Junghans 625 (with automatic assembly) are the last by Junghans produced mechanical movements and are considered very mature.

The Junghans 623.25 is the Economic variant which has only 15 Jewels unlike the Junghans 623.20. It has no date quick set and its balance shock protection only carries the favorable Epsilon Antichoc 106.

The watch is still non-revised and uncleaned.
