Best / simplest explanation seems to be that this case was produced early in the cycle, but by the time the watch was assembled, they were using the second execution dial and hands. So indeed, this looks like a "correct" second execution 1158S. One thing that we have learned about the automatic Carreras, in general, is that we cannot establish which tachy ring belongs in which execution.

So this one looks "correct", using our usual standards.

: agree though, that the time from case manufacture to final
: assembly can be pretty long for 1158s.
