I have a couple of the Ultra-Verithin cases marked Staybrite. So far, every one of them I have seen or own has also been marked Guildite, and they're all Swiss made.

I note that all UV steel cases I've seen so far are from the later Unadjusted production (554k and later). So at least post-1930, probably 1933 and later.

This has no direct bearing on the subject (wristwatch cases), but maybe will be helpful along with Jack's comments above.
