The Mark II dial
This dial was produced early for the 16520s. The major difference on this watch was the the word "Officially Certified" was left out of the dial even though the watch was rated as a chronometer. The word "Cosmograph" was now together with the rest of the writing on the top of the dial.
The subdials contained the same characteristics as the Mark I dial.
This dial configuration was also made for about one year.
