The Vintage Wrist Watch Company has dated this piece to the 1950s.
In 1948 Hamilton introduced the first of several new watch models in the "CLD" line.
While it was not marketed as being waterproof, the case was intended to protect the movement against moisture and dirt.

This particular watch is the Reardon model, first introduced in 1953 and in fact only in production for two years.
The watch has a hand-winding movement, calibre 748, which is working nicely.
The watch itself measures 32mm diameter excluding the winding crown and the lugs. The case is 14ct gold and is marked as such on the back of the watch, together with the case maker's mark S&W for Schwab & Wuischpard, the company manufactured many cases for Hamilton.

The case back is also marked with the patent number 2609655 which relates to a 1952 patent. The inventor is listed as Henri Edmond Vermot while the applicant was Hamilton Watch Company. The patent related to hermetically sealed cases.

The case is in good condition and the shaped lugs are a particularly charming feature.
The lens is in good condition.
The signed dial is in good condition with 18ct gold markers, dauphine shaped hands, centre seconds and outer minute markers.
A later leather strap has been fitted.
The watch comes in a Hamilton presentation box.
