One of the new 14/0 models in 1948 was the Hayden. It would be produced through 1952.
The Hayden featured the 19 jewel 982 movement in a 14k gold filled case. The case is most commonly found in yellow but there are also examples in white gold filled. The white versions are more scarce.
The dial is a butler finished silver dial with solid gold numerals and matching hands. With the white case, the numerals and hands are rhodium plated.
The case is interesting in that it is one of a handful of Hamilton models that featured hidden lugs. The strap is mounted underneath the bezel, in a hollowed out area. I think the case tends to wear pretty well and is usually in good shape whenever I see one. It could be because of the crystal's thick and curved shape offers some protection.
It's a fairly small watch, especially by modern standards, and could easily be worn by a woman today.
Here's a couple of shots of a Hayden I've had in my collection for quite some time.
