Notes

This watch has one of the largest movements ever made by Patek Philippe; only one other is larger. This is No. 198014, a 29''' movement made for James Packard. The other two Patek Philippe watches with large movements, No. 174623, and No. 198385, were also made for Patek Philippe's important clients James Packard and Henry Graves, and have 25''' movements. The special quality of the watch can be seen in details such as the double diamond on the balance, the sweep seconds hand in aluminum to minmize its weight, and the platinum mean time screws.
