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.

I have 2 Ebrrhard & Co Traversetolo chronographs fitted with this movement – 1 black and 1 panda. Both have blued screws and engraved (not in gold);”25 jewels” and limited cotes de Geneve striping.

Given that ETA has 4 levels available, I am curious at to which one this is, excluding COSC as these watches are not so certified.
