In 1950 the Heuer triple date calendar came out to celebrate Heuers 90th anniversary, marketed as the “Half of a Millennium” watch. The watch also spanned into 1951 being triumphed as one of the Mid-Century models. It was available in chrome (Ref 1815-14), steel (Ref 1806) and gold filled (Ref 1816-18).
