Caliber Commentary:

“Its ETA Valgranges calibre A07.111 movement that was introduced in order to replace the ageing (and also iconic) ETA 775x family of chronograph calibers (and also to better suit modern “larger” wristwatches) is heavily modified by Eterna’s engineers and is hidden inside a huge case whole 45 millimeters in diameter and 16.8mm thick.” (Source: http://www.worldwatchreview.com/2008/11/13/porsche-design-worldtimer-p6750-now-in-rose-gold-case/)
