Notes

591 - The present watch uses Adrien Philippe?s fi rst winding and hand-setting mechanism, French patent No. 1317 of April 22, 1845. The winding pinion is fi xed to the winding shaft. For winding the crown it must be turned clockwise and cannot be turned back with that typical ratchet noise. To disengage the winding in order to set the hands, the winding crown can be pulled out. Very few watches survive with this early winding mechanism without coasting.
