Prior to using the watch for the first time, the new owner needs to implement the following basic settings. He determines where the home base of his timepiece is: For this, it is necessary to set the home time, synchronize the destination time and select the IATA code of one’s own home time zone in the respective window (depending on daylight saving or standard time). Finally, the date needs to be set. These basic settings have to be implemented only once. Should the watch have stopped running, the time can be reset simply by turning the crown at 2 o’clock. To continue with the destination time, the owner only needs to turn the crown at 4 o’clock to set the time at the respective destination.
