Surely this has already been considered (and debunked?), but is there any chance these bezels all started life dark blue, and some just faded? Second, is there any other official marketing material found wherein a more descriptive term than "blue bezel" is used?
UG has different bezel colors and materials. Used in V72 and non valjoux compax. Surely mixed and matched while the company struggled to stay afloat
Fun theory and discussion. I am in the camp that the colors likely aligned as originally assumed but by the end either combination could have been sold as UG was struggling. So you may see the reverse combination in smaller numbers. This seems the case from what I have observed.
Thanks to @MarktheTime for posting. Sorry, I do not see any chance that UG offered buyers both options at time of sale. It would be too much hassle, risk, and inventory complexity (and expense) to manage such a process.
I think it is universally accepted that the above page of logos is incorrect.
The 'thin U in a box' logo was introduced in the very early 60s and the 'fat U' logo was introduced around ten years later in the early 70s.
