A Seconde Morte works like quartz and jump between two indications. The first watch with dead second was designed in 1754 by Jean Romilly. A forerunner of the chronograph. Its second hand could be stopped to measure time intervals.Yet, this required stopping the movement too. In 1776, to overcome this, Jean Moise Pouzait worked on an independent dead second watch which featured two gear trains but which was still lacking the return-to-zero function that would eventually lead to the chronograph. This watch also has a semi-chronograph function.
The dead beat second hand can be stoped on demand by the button from the crown, so a very precision time can be measured. The watch is very impressive-105g heavy in 18k gold!
