[Vintagehamiltons]

manufactured from late 1938-1948, excluding 1942-1945 when all manufacturing was for the war effort
17-jewel 987 movement
51,044 produced in yellow gold fill
5 :scared: produced in coral gold fill (I don't think one has ever been seen)
4 dial options: applied gold numerals, two-tone with black enamel numerals, luminous, and roman black zone (very rare - I see maybe one per year listed on eBay)
28mm diameter excluding the crown
38mm over the lugs
16mm strap width

IMO, this design is probably the inspiration for the current Khaki lineup as it was offered with a luminous dial. The model pictured above was never in any of the catalogs, but did appear in a number of magazine advertisements.

I like everything about that model. And you're right, the current Khaki line seems to carry daddy's genes.

I see how the Endicott can be perceived as a link between the actual military models and the modern khakis.

It has quite a large crown, Tom.
