This worldtimer continues the exciting innovation of the Jaeger-LeCoultre Duomètre line The specially-designed manual winding movement, Calibre JLC 383, acts as two watches in one. Each “wing” of the movement has its own barrel for power but sharing the same regulator. The crown winds both barrels Clockwise for travel time and counter-clockwise for home time and the escapement.

The two timezones are placed next to each other on the dial with a globe at the 6 00 position and central seconds. The home time display, on the right, is a standard dial with silver hour and minute hands. The “travel time” dial is on the left and uses just a contrasting-color minute hand with a digital jump-hour window at its 12 00 position. Dual unmarked power reserve indicators are placed below each dial. The large blue globe at the bottom shows day/night in every timezone using a rotating GMT adjustment ring.

This watch was first shown at SIHH in 2013 with the limited-edition 606.35.2J version in white gold to celebrate their new Paris boutique. In 2014, the company released the regular production version in rose gold, 606.25.20, again at SIHH.
