To have a watch assayed, you would need to take it to a professional appraiser or jeweler who specializes in assessing the quality, authenticity, and value of watches. They will examine the watch, check its markings, materials, and movement to determine its authenticity and value. This process may include testing the metal purity, inspecting the timepiece for any alterations, and verifying its brand and model.
Inside the the back of the watch there will most likely be the dates of servicing scratched in. On the movement there should be the makers name, date and often a serial number. Libraries and websites (example below) carry catalogues and books on antique time pieces and should be able to tie the serial to a date. A good watchmakers or auction house will also be able to tell. If the watch case is English and the case is either silver or gold, the hallmark system will indicate when and where it was assayed and the karat weight of gold in the case; there being only one value for sterling silver. Often a makers or sellers case and face could be fitted with a variety of different movements, altering the value of watches that look very similar. The design of the case and any pastoral scenes, machine turning, enameling etc on it could also give a rough indication of age, as can whether the winding is by key or button. A fusee movement is often an indication of quality.

A sunflower hallmark on a gold fob watch typically indicates that the piece is associated with the Birmingham Assay Office in the UK. The sunflower symbol was used to denote the year of hallmarking, specifically for items assayed in the early 20th century, particularly around 1900. It serves as a mark of quality and authenticity, indicating that the watch meets specific standards for gold content.
Have it assayed by someone who knows how. It's not really something you can do yourself at home.
The hormone is called hCG or human chorionic gonadotropin. It is also called "human growth hormone."
To protect yourself assume it is not until you have had it independently assayed. However China is more than capable of producing genuine gold objects.

A lion passant on a pocket watch case typically indicates that the item is made of precious metal, specifically gold or silver, and has been assayed in the United Kingdom. The lion passant represents the standard of quality, confirming that the metal content meets legal requirements. The "warranted" mark suggests that the manufacturer guarantees the metal's purity and authenticity. This hallmark system helps protect consumers by ensuring they receive items of specified quality.
Different countries have different ways of marking gold and silver objects. In the UK objects made of these metals are assayed by the government and stamped with an assay mark.
The bracelet is stamped with an anchor, the date letter g, and the makers mark is DK. This means that the bracelet was assayed in Birmingham, England, and is dated 2006.
It means precisely that karat/percentage. In the case of 14 karat, 58.5% pure. I believe the statistic is, if it's not assayed to be "plumb", it can be as much as 2.1% under/over.
