Lange & Sohne released the Saxonia Dual Time watch. This is the first GMT for the Saxonia line. The hour hand indicating the local time can be changed by the hour. There are two push pieces, one at 8 o’clock and one at 10 o’clock. The push piece  at 10 o’clock advances the time by the hour, the push piece at 8 o’clock allows the hour hand to go anti-clockwise in one hour increments. The watch is available in rose gold and white gold with a 40mm case.
