The Gold content should be stamped on the inside caseback; I'd have a qualified jeweler open it to have some good pictures taken if you really want to to know more about it. Also, you can probably send the serial numbers to Patak directly to get information on when it was made and what it contains.Patek Philippe Pocket watch
I would like to know when this watch was made?
Is the gold 18k or 24k?
How much do these sell for?
