That is very good information. Learned something new today.
Question - would Swiss law be similar to French law here?
In the US, it was much different back in the 1950’s and 1960’s. I have solid gold buckles for both Omega and LeCoultre from that period.
Both are hallmarked on the buckle and tang with karat gold markings (“14K” and “18K”). Gold plated buckles for both brands have no markings at all other than the brand names.
Hope this helps,

I aknowledge I do not know as well the Swiss law. But considering gold plated watches and buckles, I am under the impression there are similitudes with the French law, but also differences.
First, solid gold must be stated by a precise hallmark. I have seen online so called brand made gold buckles without any hallmark, but have always considered them as suspect.
Another well known similitude is the fact solid gold is indicated by numbers (750 for instance) or by "imaged" hallmarks (eagle head or Helvetia for instance). The use of numbers is much recent in France though - although it has been used in the past.
Third, gold plated has its own hallmarks, which are pretty different from solid gold. In France, the hallmark stated a number of microns and/or the maker in a square - the maker's name is a lozenger for solid gold. Concerning Swiss gold plated watches, I do not know the rules and can only rely on my limited experience. But as far as I remember I have always found a clear hallmark stating the micron content. Omega Swiss made 80 microns cases also often indicate the way it was produced with a "plaqué or L" (L meaning "laminé", that is to say a gold sheet has been applied to the base metal, by distinction with methods using electrolysis). These watches generally also indicate the maker in a square with rounded angles.
I aknowledge I do not know much about gold plated bucles. I know small French products (less that 3g as far as I know) do not have to have a hallmark, wether they are solid gold or only plated. I would say that many buckles weight less than that. But, as I already said, all the genuine solid gold French made buckles I have seen - and I think it is also true for Swiss made ones - had a clear hallmark. I am
aware there are interesting examples that could be out of this rule - see for instance this very informative thread launched by
@omegastar - but I have not seen any in person.
Now concerning gold plated buckles, my impression is everything is possible! I would not try to set any general rule. But it is worth noticing that a "plaqué g" buckle belongs to a precise rule in France as I said above. I wonder like you if it is also the case for the Swiss law. I would be surprised if the same distinction between "plaqué" and "doré" would occur. But "plaqué g" could still obviously be a specific Swiss hallmark.
Maybe someone more knowledgeable than me could give an insight about the Swiss law concerning those issues.
