It is not clear to me which horizon it uses.
(Could use both).
The only purpose I can imagine for this instrument at sea
(besides artificial horizon if it has one)
is observation from some very shaking platform.
I have no experience in sea with an ordinary sextant
(but going to try it in July from a small boat)
so I can only guess.

It does not look like something related to a periscope:
that kind of sextant is rigidly attached to the periscope
is it?

And this one has special shoulder straps.
And some misterious wired box...
