Notes
This watch is fitted with the first stem-winding
system designed by Adrien Philippe (French patent
No. 1317 of April 22, 1845), without the possibility
of turning the crown anti-clockwise during
winding therefore this watch incorporates the
highest technologies for the tinte in the field of
horology among which are important features such
as the straight line lever escapement and the stemwinding
system.
