1980s Glycine caseback markings. Military?

I am waiting for this 1980s Glycine I bought on ebay, almost a Combat but with a different handset and branding. A nice little field watch.



I wonder about the caseback markings : I doubt they are fake because the watch was cheap and not advertised as anything else than a regular glycine. I posted in the MWR forum, nothing. It really looks like a Swiss cross, the "Old Cross" of the vintage Victorinox knives. A little too impersonal to be commemorative markings. I never saw it anywhere on a watch caseback. Anyone has an idea?

Could it be Swiss AF markings from the 1980s? A more recent forgery?

I've seen the Gallet controversy...
