Key Features

Sophisticated JAMES NARDIN ‘Seconde Morte’ wristwatch with a two wheel system and jumping second. This conversion wristwatch contains a super rare original movement, made by a Nardin family member back in 1870’s.

The function is called “Seconde Morte” – a ‘dead’ jumping second that does not run as usual, but jumps like in a quartz watch except the timepiece is mechanical and top-grade from the 1870’s. Its modern counterpart is the Jaeger-LeCoultre Duograph, which has a dual-barrel and double wheel train movement with jumping seconds – and this watch uses exactly the same scheme. In fact, this device contains two mechanisms that run simultaneously, united by a common oscillatory system.

The watch has two spring barrels, two wheel trains, and a separate wheel train for the dead-beat second hand. The crown winds in two directions for the main escapement barrel and for the seconds barrel, and there are two additional buttons – one for setting the hands and one for stopping and starting the seconds feature.

About The Ulysse Nardin Dynasty

Ulysse Nardin was founded in 1846 in the Swiss province of Le Locle, by the talented watchmaker Ulysses Nardin. Soon after the company started production, they began to concentrate on the creation of high-precision timekeeping devices, in particular marine chronometers, as well as complex watches containing minute repeaters, perpetual calendars, and chronographs. Keeping the jewellery and decorative component to a minimum, U. Nardin found that the formula for success in the art of precision mechanics was functionality, accuracy, and reliability. They are one of the few companies that has remained in continuous production for over 165 years. The James Nardin company comes from the same lineage as Ulysse Nardin; indeed, there were quite a few famous watchmakers in this family.
