Gold Pocket Watch Hunter Case

What is my cyma solid 18k gold swiss made pocket watch worth?
83 grams of 18K gold style Hunter
Night Last I read about a way to understand the value of gold. The article says Multiply the weight of gold (83 grams) per the current price of gold (in ounces). For a play 18k, then divide by 41.5. This is the $ value. As for the amount of dealers will pay they say Multiply the dollar value of 0.50 and 0.80. A fair price is in this range. The formula takes into account the percentage of gold in jewelry from a Karatag particular, with the ratio of 31.1 grams to a troy ounce. The high end of the last step is for large quantities of gold. Hope this helps. PS Solid Gold 24K.
