Now I am a bit confused: so a dial like this isn't correct for an early 40 watch (1940-43)?
You are showing two different watches with different dial executions.
Look at the 6 in 60 seconds. One has an open 6, the other a closed one.
Both dials are imho genuine UG. The question is, if the first one is correct to the watch.
Anyhow there's also multiple examples of closed 60s in sala for early 40s, plus the example I posted above from the private sales section.
