I have asked a few people about this Hamilton case and so far it seems to a uncommon example. The case is sold 14K heavy for a 10S at 28g (with thin crystal) as you see beautiful condition, can anyone tell me more about this one, I was told it is similar to a Masterpiece case.

This was the "Gould," which appears in the catalogs from 1937 through 1940. Note that the catalog states there was a choice of dials.

I have the same case. This is a rather late case.

The true Hamilton Masterpiece was made in the early 1920s. You will find watches whose dial say Masterpiece even in the 1950s but the quality of
these watches are much inferior to earlier ones.

In the late 1950s and then up through the 1980s "Masterpiece" had a very different meaning at Hamilton -- it was used on watches sold specifically to corporations as employee incentives or rewards. You'll find the term on all sorts of watches, including gold-filled and rolled gold-plate. It no longer had the quality connotation of the early Masterpiece watches.

Thanks for the information on my “Gould” cased Hamilton, This one is inscribed with a presentation for 1940 which pins it down to the movement year and Rene’s information
The watch has been in storage for sometime and hence survived in such nice condition
