             1.  11XXX   /  25XXX  ;
             2.  40XXX  /  49XXX ;
             3.  51XXX  /  57XXX ;

             6.  85XXX  /  96XXX .
             Three watches with a 4 digits S/N  were also recorded .
NOTE  : 
           1. The fame acquired during the prewar period on the German market made Glycine
               one of the largest supplier of the 3rd Reich .
           2.  Glycine , togheter with Arsa and Helios , is certainly the most common D.H. available today .
           3.  Batches and S/Ns are purely indicative .
