VIDEO: How Does A Jumping Stop Seconds System Work?

Jaeger-LeCoultre Duometre Described by Jaeger-LeCoultre as a “masterpiece of micromechanics,” the Duomètre Quantième Lunaire features an exceptional Dual-Wing movement with two independent power reserves; one measuring the time (regulated by Escapement and Balance), the other powering the functions, and an exclusive jumping stop seconds’ system to boot The jumping stop seconds system (featured in the video below) ensures accuracy to the nearest 1/6th of a second when setting the watch, a horological achievement for Jaeger-LeCoultre. It sits alongside an additional sub-dial, which showcases the date and age of the moon. WATCH THE VIDEO

The genius of this timepiece also lies with its Dual-Wing movement, which uses two power reserves to supply the timing, along with the functions (hour, minute, seconds hands and date/age of the moon for both Hemispheres). Both these power supplies are synchronized through the jumping seconds’ mechanism, which is driven by the escapement. When you turn over the watch, you’ll see that the calibre is divided into two sections or ‘wings’ and on each side sits one barrel, with its mainspring, see the video below. WATCH THE VIDEO

Both these power reserves are wound by the crown, which needs to be rotated clockwise for the timing barrel and anti-clockwise for the functions barrel – an outstanding piece of watchmaking!
