This example of the ETA Valgranges caliber A07.161 was found in a Porsche Design Worldtimer. Other watch sites state that this watch model is powered by an ETA Valgranges A 07 111 with Eterna module. However, the actual movement inside is stamped ETA A07.161 (A07.111 is the base).


Other variations of this movement include:

  • A07.111 calibre: hours, minutes, seconds, date
  • A07.161 calibre: hours minutes, seconds, date, power reserve
  • A07.211 calibre: hours, minutes, seconds, date, chronograph
  • A07.171 calibre: hours, minutes, seconds, date, 24-hour hand, time zone

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:
