Notes

An almost identical watch, No. 109232, also with early use of the Guillaume balance, was sold by Antiquorum Hong Kong on November 25, 2006, lot 67. The inscription "Adjusted Extra" on the bridge of the movement refers to the high finishing of all the parts of the movement. For a note on the Guillaume Balance, see opposite page.
