Hi all. I purchased a Universal Genève Aero-Compax, with original dial (doesn't have sword hands) for a pretty compelling price - movement looked clean, case good, dial was NOT repainted, and I discovered that the "dual time zone" dial doesn't move. I can adjust it with the 9-o'clock crown, but it remains static. When I adjust it (after a recent cleaning), I feel significant resistance, as if it should be connected to the main mechanism, rather than an easy turn, leading me to think that it should be a true dual-time zone. I've read several forums, and the word that keeps popping up is "memento" dial. Is this just a euphemism for an originally-designed function that no longer works? I find it difficult to believe that UG would have designed this watch for pilots, and it not have a working 2nd time zone. It's not a sophisticated feature. Just need a clutch on the 9-oclock crown that disconnects the regulator from the main mechanism for adjusting, and have a simple connecting gear from main mechanism to transfer force.
I'll include images of the movement in my next posting below.
