I believe currently four stamps/marks are a requirement on a precious metal watch case in Europe

I was curious about this when I bought my ochs und junior moon phase.
Here is an interesting blog post from Ochs und Junior regarding the process of getting their cases assayed.
And below are pictures of my ochs und junior in silver with the four marks (from left to right):
1. Brand/responsibility mark
2. Brand's indication of fineness
3. Vienna convention statement of purity
4. Swiss Bernard dog (with 'Z' indicated, I believe for Zurich)
(The darkness on/and between the lugs and on the top of the case is just some natural silver patina)

Think they'll be assay office marks

Pretty much all precious metal items have them. They tend to be country and even city specific Regards JML
Correct!

These are the Swiss gold hallmarks (proof of authenticity), and that's what they look like. ...
Is the 750 marker
