You wanted to promote discussion. I appreciate that these are pocket watches and not a wristwatch like yours. Furthermore, it’s a different part of the bezel. However, they’re from the same period and they show the style and use of enamel (one is niello of course).
Respectively 1919 (35.5), 1921 (19'''), 1922 (23.7).
