and it says:
"The star on the dial indicates the Teddington model as the wristwatch that carries the same movement that was awarded a prize as the most accurate ever at Teddington Observatory"
In 1940, Omega was awarded the best result in history at the Teddington Observatory for a wristwatch and you can now own the very same king of movement. Visit an authorized dealer and pick your Teddington model and you will then own
the officially certified watch!"
Just a side info: the watch would cost USD 50 today, inflation adjusted.
