This prototype looks as though it would be water-tight for use underwater. It was never produced in series or pre-series. It was probably meant to replace the “KRAB” underwater housing for the LOMO LC-A and was followed by another prototype model, the Akvakon-2 which was motorized, with built-in flash, and fully automatic exposure.
