I can only tell you that most of the JLC and Omega Vintage are very affordable, they just don't are, sometimes, not easy to find.
And both are full of charm, too.
It is just a question of time, and Hunt.
Cool, no?
As for the Duo shots, this is one of my habits, Ruckdee, to compare watches.
I do so in my collection, and in my posts.
Best, my friend.
