  • Identification: Setting lever and setting lever spring listed in the Newall Fingerprint Catalog of 1951 and in the Paulson of 1950 as Hahn 8 3/4''' (round). An advertisement by Hahn in La Fédération Horlogère Suisse from 1925 mentions an octagonal movement with 8 3/4''' and shows a very similar one with 7 3/4'''. This is most likely the 8 3/4''' octagonal movement mentioned.
