Notes
Movement based on the American invention patent No. 61 207, delivered on 15 January, 1867, to Jules Jürgensen, Copenhagen and Le Locle, for a “Improvement in stem setting watches” and on the American invention patent No. 161 239, delivered on 23 March, 1875, to Jules F. U. Jürgensen, Le Locle, for a “Stem-setting Watch”.
For setting the hands, throw up the glass cover and turn the pendant bow close down upon the glass. In this position the winding crown sets the hands. In all other positions the crown winds as usual.
