Hiho Abel, an interesting theme this week!
I don't usually pay attention to the solid case backs of my watches, as there is usually nothing much to see😂.
The first that came to my mind was Omega Snoopy but I will skip since you and some others have shown 👍🏻🥂
A few that I looked at just now and found interesting are:
Couple of Bulova's made during the war

Rado Cpt Cook re-issue and a vintage Omega SM

A JLC Reverso and Urwerk 103

Zenith Pilot Brz and Habring2 Endurance (sorry, out of focus, did not realise until I kept the watches 😅)
