I think it is all original dial and case looks good also.
Lume plots are all in place and all aged. I see nothing wrong with any markings. The swiss at 6 marker sometimes looks like it is touching but it doesnt. It is the angle.
Plexi non Omega is no problem imo.
800£ is on the high side. If you like it a lot....try get it for 600.
Was it serviced recently?
They say it was fully serviced in-house few weeks ago, and explained what was done as the following:
>>
- We put a new Sternkreuz crystal on the watch, thus not with the Omega logo.
- The strap and buckle have the Omega logos, but they seem to be good quality after market, thus not original Omega.
- The service was done in-house by one of our affiliated watchmakers. When we service a watch, we first check the functionality of the watch for any issues, then take the strap/bracelet off the watch and disassemble the watch.
- The case and crystal (and bracelet if metal) is cleaned in an ultrasonic tank separately from the watch movement. The movement is checked for tolerances and then fully disassembled and cleaned in a watch cleaning machine.
- After cleaning, the movement is reassembled with new oils and greases and gaskets if necessary and is then timed and adjusted and checked for functionality before being replaced in the case.
The watch is then tested for 7 days and readjusted for time before being listed and sold.

Sounds legit and honest, so I think just ask if the dial has been restored and maybe a higher res photo?.
As a few have mentioned, this one doesn't seem obvious enough and I'm having difficulty finding an exact comparison.
Added couple more photos.
