The Panerai OPIII. It is based on the ETA 7750-P1, which is basically the ETA 7750 but with the chronograph functions removed. Basically it is not a review but more photography learning.
Even the movement spacer is finished with circular graining.
Movement holder tab and screw.
Three movement holding tabs.
21 Jewels, Swiss Made.
Winding stem removal button, I think.
The rotor, signed (many many times).
The inside of the case back is nicely decorated with circular graining.
Swiss Made. :)
