Notes

The present watch is one of very few known with a ?double? regulator to so far appear at auction. Two others are known, No. 100019 and No. 109232. The two regulator arms do not work independently but are fixed in position, the regulation is adjusted using the familiar ?swan-neck? regulator, the other arm showing the degree of regulation. The inscription "Adjusted Extra" on the bridge of the movement refers to the high finishing of all the parts of the movement.
