It looks indeed very Heuer to me ;-))

: I recently bought a plastic display and a Heuer dealer stand. The
: seller got these stuff in a lot from an old Heuer dealer. The
: seller told that the old dealer sweared that the red display
: came from Heuer. It hasn't any markings or codes on it, the
: front has a recessed space for a large sticker that (I suppose)
: was never attached.
: Have You ever seen one? Would also be interesting to see other
: vintage displays pictures.
: Thanks!
