Regarding the brushing - having examined mine just now there is not much metal in the actual case so it would be a skilled job to recreate the starburst brushing effect.
I've spoken to Simon freese about this finish on other Omega tonneau type cases and he said you have to be very careful when lapping a starburst finish not to remove too much.
Sherbie mentioned the gasket colour - not sure if mine would be classed as white/blond or pale green.
So mine might be NOS or a very good refurb, either way I bought it because I like the look of it on top of it having day,date, 24hr which is more useful day-to-day compared to my Speedy Pro.
Plus it has a great movement - the Omega 1045 (lemania 5100)
Lots of intersting reading on here
