ETA Valgranges Caliber A07.211

The ETA Valgranges caliber A07.211 is a Swiss made automatic chronograph watch movement. The Valgranges family is based on the ETA/Valjoux 7750.

Valgranges A07 VS ETA 7750:

One of the big differences between the Valgranges and the 7750 is the diameter. The 7750 is 13.25”’ (about 30mm) and the A07 is 16.5”’ (36.6mm). This makes it a good option for larger watches such as the models Invicta produces.
