Aleksandr,
"but I had no way to check that the salt water did not find its way
inside the worm cover (the worm is completely enclosed).
Bill Morris says that this is unlikely, unless you submerge it completely
in the water. Still it was somewhat disturbing that I cannot SEE the worm
and inspect it to make sure that it is clean."

Just spray a little WD40 inside the enclosed worm after each cruise and you'll never have any
issue with the SNO-T worm (the same advice would apply to a Freiberger Trommel sextant).
As for sand and dust in a desert region, I don't think it (nor any other marine sextant btw) was designed for this very specific use.
I also own a SNO-M but it's less accurate than the SNO-T and also far less confortable to handle. The thumb rest featured on the back of the SNO-T is really ergonomic and allows long shooting sessions without excessive tiredness of the operator (specially for lunars).
