Gold-plated watches will have a stamp to indicate the amount of gold used followed by a G, F stamp symbolizing gold filling. Quite often, the entire watch, including the case back, will be covered with gold, and the inside of the watch case back will also indicate that the watch is gold plated. All real gold jewelry is stamped with a seal that identifies its contents and the manufacturer. The stamp of a gold pocket watch is likely to appear on the back of the pocket watch.
The fineness or purity of a gold item is measured in carats, which run on a scale of 9 to 24, the latter meaning the highest purity. Solid gold pieces are usually stamped with their carat number only. For example, an 18 carat item should have a stamp such as “18K”, 18kt or “18KP”. Gold-plated jewelry is made by wrapping a very thin sheet of gold around a base made of another material, such as nickel or brass.
Although you can't tell if a pocket watch is real gold at a glance, you shouldn't buy it if it's faded in any way. Because they are slightly less expensive compared to solid gold watches and more attractive when compared to gold-plated watches, gold-wrapped watches will provide you with a wider scope of use. The best way to get a real gold pocket watch is to buy one directly from a well-known retailer or manufacturer. The gold acid test lasts less than a minute, usually free, but it will most likely leave a stain on the watch.
Sometimes gold-filled parts are sold with a warranty stating how long the top layer of gold will last before it wears out. To perform this test, rub your gold watch on a black stone to leave a mark, and then apply nitric acid to the mark. In this case, you should take it to a professional jeweler who will have the equipment to study the watch with magnifying equipment. The problem with acid testing is that to tell if an item is filled with gold, you'll need to scratch it relatively deep to see if there's another material under the top layer of gold.
In addition, gold-plated watches have very intricate case designs and some gold is placed in the available spaces between the contours of the delineation to give it a more natural look. These automatic tests may seem invasive and rigorous, but you should know that none of them will damage, degrade, or cause your pocket watch to devalue. Gold-plated items are similar to gold-plated pieces in that they are not solid gold; however, gold-plated jewelry has a much thinner gold coating. If the watch is very old, the original markings may have worn out and cannot be seen with the naked eye.
The most efficient and time-saving way to buy a real gold pocket watch is to buy from a well-known and reputable supplier. If you intend to buy or sell a gold pocket watch of any type, you must ensure its authenticity. Pure gold watches are exemplary options if you want to attend a large formal or informal meeting, but other than that, you may want to employ them in minor uses because of their high value.
