Скачать или смотреть Acid Testing Gold Omega, Lanco, IWC, and Eterna Watches

As value of the US dollar collapses the price of gold is going up. How much is the gold in your vintage watch worth? And is it solid gold or just gold plated?

In this video I use the Agusta Technic precious metal acid testing kit sold by Bijoutil in Geneva to test four solid gold watch cases for gold purity. One of the watch cases (the Lanco) is 14K and the other three (IWC, Eterna, and the Omega prototype) are 18K.

Here's a link to an outline for a book that I'm working on about the Omega prototype if you're interested:

All of the gold samples respond to the acid tests exactly as expected.

I purchased the test kit from bijoutil.ch
