Those seal the ports used for purging and nitrogen charging. My guess is that all Habichts with those screws at least started out waterproof. Habichts without the screws probably were not.My earliest Habicht brochure dates from 1982. Photos of the binoculars in that brochure do not show the screw heads and there is no claim made for full waterproofness. Instead they are described as "dust and splash-proof". At the time "splash-proof" was another way of saying " pretty well sealed, but not waterproof".</blockquote>
