Hi there,

I am trying to locate this Zodiac model that belonged to my grandfather without any luck so far. Unluckily it does not show any serial number on the case nor the bracelet that would allow me to track it down.

I can only mention that it's a stainless steel model, Automatic, Antimagnetic, Water shock resistant as per case info. Probably 70s but no clue really. I am attaching couple of pictures so perhaps someone may help me with this model's search.

Appreciating your support :)

It is 722 910.
I'd date this watch somewhere mid 1970s. Saw similar model in Spanish 1974 Catalog.

Remove the bracelet under the 6 and that is where the serial number is.
