The watch producer Eterna – since 1998 licensee partner of Porsche Design – has designed and built a special movement module in its manufacture based on the ETA Valgranges calibre A 07 111 for the Porsche Design Worldtimer P’6750. The module extends this movement by the addition of an intelligent GMT function. The three hands in the centre of the watch display the time in the time zone in which the wearer currently finds himself.
By means of discs rotating behind the dial, the movement additionally displays, via two dial apertures, a reference location and the present time in the corresponding time zone. The second time zone runs in synchrony with the main watch time.
The setting of the reference location can be corrected by means of the crown at the two o’clock position. Transfer of the time at the reference location to the hands is permitted by the button integrated in the crown at two o’clock. While the time zone function of the watch is being adjusted, the automatic movement continues to run without any limitation – not one single second of the original setting is lost when the time zone is changed. Self-explanatory abbreviations are used to designate the reference cities. These three-letter codes are explained by an engraving on the back of the watch case.
The crown at the four o’clock position is used to adjust the minutes and the hour hand in the centre. In addition, this crown can be used to wind the watch. The“Clous de Paris” decoration of the crowns is not provided for aesthetic reasons alone: the decorative structure makes for a better grip on the crown.
The design of the Porsche Design Worldtimer P’6750 is typified by the usual under statement. Simple cylindrical forms shape the watch case which is made of the typical Porsche Design material, titanium. The typography, styling and colours of the dials emphasize the functional character of the watch. In addition to the case in matte titanium, another version in titanium with a black PVD coating is also available. Both versions are fitted with a black caouchouc strap with a latitude and longitude pattern in profile on the inside. This makes for enhanced wearer comfort by allowing air to penetrate between the skin and strap. The folding clasp of the strap is also made of titanium.
