Pretty sure it's not a date/serial range issue, and that almost any 60/70s bezel could be "ghosted", depends on amount of exposure to strong outdoor light. I don't think it's like tropical dials, which were "probably" due to a a particular black paint used for a time. I've seen Sifferts with last execution dials and early 2446 1st executions with ghost bezels too.

: Just for fun, I'm also showing a ghost bezel that I once owned, on
: a Skipper. This seems to have happened around 1968 / 69 . . .
: serial number range from 110xxx into the 140xxx range.

: So by all means, "post a ghost" if you are so inclined.
