Good questions Dune.

Karat ('K" or "Kt")- term used to define the PURITY of gold

Carat  ( "Ct")- term used to determine WEIGHT of gem stone

In the USA 'Karat' purity marking are required, in the EU the percentage of pure gold is a requirement hence 75% pure gold  (18 K being 75% pure gold) would be marked .750 in the EU. Makes sense that a modern manufactured product would carry both markings.

BTW - beautiful time piece
