Хотел обратиться к Вам г-н "Butchara" процитировав фразу; "hollow gold (дословно: "полое золото")" и поинтересоваться, известно ли Вам, есть ли у вышеперечисленных продуктов общепринятые клейма, именники, или все эти нюансы скрыты в коде-артикуле модели часов.
Благодарю ещё раз за внимание!

Насколько я знаю, "полое"
(дутое) золото ничем не отличается от обычного золота и носит на себе совершенно стандартные и официальные пробы.
Оно же просто
пустое внутри, а не ненастоящие
Gold Filled
Gold filled, sometimes known as “gold overlay” or “rolled gold”, is not the same as karat gold. Gold filled pieces have a layer of karat gold which is affixed or bonded to another metal, usually brass or similar alloy. Clearly, this is far less valuable than if the piece was made entirely from karat gold as the actual percentage of gold in the entire piece will be greatly diminished while the gold used is always less than the metal used in the bonding.
Nevertheless, gold filled jewelry may still possess a hallmark so watch for the suffix “GF” or “10K GF” – the GF obviously stands for gold filled.
Gold Plated
The hallmark for a gold plated item will use the suffix “GP” and if you see this on a piece it will mean that the gold is only applied in a very thin layer. The minimum standard to be referred to as gold plated is 10K gold applied with a thickness of more than 0.5 microns – this is so thin you could not discern this with your naked eye – it’s about 20 millionths of an inch!
