Notes

Superbly adjusted Swiss watches of the period, and particularly those of Patek Philippe, were signed "EXTRA". This watch came from a series of watches destined for the 1930 and 1931 Geneva Observatory Trials and most likely took part in one of them.For note on Guillaume balance, see lot 720.
