I don't know who or where you called Warren, but certainly speaking to a dealer or central office in the US won't reveal any results, they have little information of their vintage time pieces. I can't see how they could help you anyway over the phone!?!

That's not to say that TAG Heuer don't have a keen interest in their history. Their vintage 'Brand Heritage' Dept is based in Switzerland, and is excellent. They are very interested in their history, and have poored millions into the TAG Heuer museum, and vintage department workshops. They have built up a wealth of knowledge. If you look at the threads higher up on this forum, you will see that 30 odd of Heuer collectors from this forum have just come back from the Heuer Summit, hosted by TAG Heuer and their Heritage Dept, and Jack Heuer. Needless to say, they do hold extensive records.

It's fair to say that the Golden Hours pocket watches are very well documented, and unfortunately, the pocket watch you have isn't part of that range.
Just to answer your queries.. old Swiss pocket watches can be picked up for next to nothing, they were made by the shed load, so aren't rare.
As for the case, I don't know if it's gold or not - you said there were no markings, so I don't know. (any assay markings? - if so, there will be a date marking) But, unfortunately, it's probably fair to say that it's not genuine. What is more of a bummer, is that someone tried to make a box to look genuine too, and included genuine booklets. This isn't a case of an innocent refinished dial, but someone trying to hookwink an innocent buyer. so, I'm really really sorry about that.
