The dial reminds me of the 1st Gen Nivada Antarctic from 1958.

Good catch! It does, and is an uncommon variation on the Zenith bumpers.

Stumbled on this thread by chance (as I don't follow Zenith vintages, and I don't want to open another hole where money disappears 😀), but what struck me was the the design of the 3-6-9-12 hour markers that look exactly the same as on the Omega golf ball dials.

Maybe they both used the same dial maker.
