The photo is not my watch. I still assume these are probably re-branded Orfina watches. And yes, they used Valjoux 7750 movements.

I'd assume it was a re-branded Orfina.
I've owned a lot of early G10 watches, and still never seen an early Navigator like this.
In that condition, I'd be thinking £200 plus.
If it's a 60's/70's Dynamic then it will be a "front loader" which requires a crystal lift to compress the crystal and insert. You should be able to get a crystal from Cousins or eBay, but make sure...
That appears to be an original case back which has been skimmed. This can be confirmed by using a set of calipers.
I think selling that dial would certainly help a lot to afford a new dial and hand set. Those Deluxe dials are very rare.
Not a sub-seconds watch, but it could have been a re-dialled 6B/159.

Looks good to me. You can probably get a crown for £20 odd. Lume appears to be the usual MOD mint-green tritium; it's part of the history of the watch.
It's a civilian version. Can't be very new if it has an ETA movement. Not sure of date of manufacture.
Is it a date model (Navigator)?
You can leave the date wheel on. Just be very delicate and find yourself a suitable, clean work surface. Hand setting can take a little practice.
I've replied elsewhere, but yes, it's the wrong movement. The 555 is from the mid eighties G10 watches. A reasonable substitution for the 955 though, but a 955 would be preferable.
I thought that price was a bit excessive. Not sure how you'd get one of those second hands replaced.
As its a relatively rare and valuable, watch, I'd personally aim to buy a donor with with a 536 movement. It may be as simple as a circuit swap to fix your movement.
There is no straight answer for this question, as the part sizes vary depending in what year of model. You can measure with calipers.
On more recent models, for the movement holder gasket, a 0.80...
That should be fine. The only thing you need to check is that the wheels/pinions are of the normal length. I bought some 955 movements recently which have a shorter second wheel pinion, so I had to...
