One example is the Paxton. In 1956 it was the Paxton B. I posted on the B model in March... You can see it here. The non-B Paxton was introduced the following year and made for two years.

Anyway - the two models are identical from the outside and come in a 10K rolled gold plated case with a stainless steel back.
I just picked up a Paxton project watch. As received it was very dirty and the crystal needed to be buffed - which I did prior to taking the shot below.
Inside you will find an A Schild 1200 movement, known in Hamilton parlance as a 17 jewel 673 movement. This one was very dirty but would run - which was a good sign that all it needed was a cleaning. You can say what you want about the Swiss movements Hamilton used... they're not the same quality as the US-made movements - but they are still very robust movements in my opinion. And they are very easy to work on (excluding the Buren micro-rotors - I'm not a fan of those).
This watch had a broken "set lever spring", also know as a "set bridge". It serves as a detent and holds the stem out or in when setting the time or winding. As you can see, the one on the right is the broken one - I happened to have a spare.
And here's the finished product, all cleaned up and on a nice croc-grain leather strap. The white finished dial has an interesting patina forming around the circumference and the numbers. I might have been able to clean it off but I kind of liked it's authenticity and didn't want to risk losing the crisp printing in the process. A dial is only original once, you know.
