Lot Essay
With Patek Philippe Extract from the Archives confirming production of the present watch with enamel dial and independent dead center seconds in 1882 and its subsequent sale on 8 March 1884.
Some 60 Patek Philippe watches are known to feature independent dead bead centre seconds. The present watch is fresh to the market and is one of only six watches featuring independent dead bead centre seconds with a subsidiary dial. It is furthermore the only one among the six in a half-hunter case.
The independent dead seconds mechanism requires two going trains, one for the movement and one for the sweep centre seconds hand, allowing it to be stopped without stopping the main train in order not to interfere with the accuracy of timekeeping. The invention of this mechanism is attributed to Moise Pouzait, Geneva 1776.
Adrien Philippe's independent dead seconds mechanism (Swiss patent No. 1017 of 23 May 1889, illustrated and described in Patek Philippe by Martin Huber & Alan Banbery, p. 53) varies completely from Pouzait's design. Moving the seconds train over the center bridge created more space, thus allowing a larger balance resulting in better timekeeping.
A similar, hunter case watch is illustrated in Patek Philippe by Martin Huber & Alan Banbery, p. 195.
