: Logan,
: I know little about the Le Jour version if I'm honest, I've never
: looked into them. Did Le Jour have it's own factory? If so, it
: would be a best-guess that they made it with shared parts.
: It is interesting to note that my research shows there were 2
: slightly different Heuer Ref. 12's.. one with a large shield one
: with small, different length hour markers and the position of
: the lume dots on the dial also differed..

: As for the Le Jour having a different dial.. again, I know little
: about them, like the Heuer version, there may have been
: different Le Jour versions too - but that's just a theory.

: Two differing Ref. 12's..
