Eterna presents the world premiere of the Porsche Design P'6750, a model capable of simultaneously indicating the time in two different time zones. A crown located at two o'clock with an integrated pushpiece allows instantaneous interchange between the two indications. The movement developed by Eterna for this model is based on the ETA Valgranges A 07 111 calibre. The module developed adds the world-hour function to this movement. The central hands indicate the local time, while the two discs rotating behind the dial indicate the name of the location and the current time in the corresponding time zone, which moves in synchronisation with the main time. The desired location is set with the crown at 2 o'clock. The time of the location is transferred to the central hands simply by pressing the push-button integrated in the crown at 2 o'clock. Three-letter codes explained by an engraving on the case back, made of titanium, are used for the indication of reference cities.
